特異性

The antibody immunogen shares 90% homology with ARRB2 (P32121) which has similar MW than ARRB1. Therefore, it is likely that the antbody will cross-react with ARRB2. However, we haven't performed any experiment with recombinant protein to confirm this.

機能

Functions in regulating agonist-mediated G-protein coupled receptor (GPCR) signaling by mediating both receptor desensitization and resensitization processes. During homologous desensitization, beta-arrestins bind to the GPRK-phosphorylated receptor and sterically preclude its coupling to the cognate G-protein; the binding appears to require additional receptor determinants exposed only in the active receptor conformation. The beta-arrestins target many receptors for internalization by acting as endocytic adapters (CLASPs, clathrin-associated sorting proteins) and recruiting the GPRCs to the adapter protein 2 complex 2 (AP-2) in clathrin-coated pits (CCPs). However, the extent of beta-arrestin involvement appears to vary significantly depending on the receptor, agonist and cell type. Internalized arrestin-receptor complexes traffic to intracellular endosomes, where they remain uncoupled from G-proteins. Two different modes of arrestin-mediated internalization occur. Class A receptors, like ADRB2, OPRM1, ENDRA, D1AR and ADRA1B dissociate from beta-arrestin at or near the plasma membrane and undergo rapid recycling. Class B receptors, like AVPR2, AGTR1, NTSR1, TRHR and TACR1 internalize as a complex with arrestin and traffic with it to endosomal vesicles, presumably as desensitized receptors, for extended periods of time. Receptor resensitization then requires that receptor-bound arrestin is removed so that the receptor can be dephosphorylated and returned to the plasma membrane. Involved in internalization of P2RY4 and UTP-stimulated internalization of P2RY2. Involved in phopshorylation-dependent internalization of OPRD1 ands subsequent recycling. Involved in the degradation of cAMP by recruiting cAMP phosphodiesterases to ligand-activated receptors. Beta-arrestins function as multivalent adapter proteins that can switch the GPCR from a G-protein signaling mode that transmits short-lived signals from the plasma membrane via small molecule second messengers and ion channels to a beta-arrestin signaling mode that transmits a distinct set of signals that are initiated as the receptor internalizes and transits the intracellular compartment. Acts as signaling scaffold for MAPK pathways such as MAPK1/3 (ERK1/2). ERK1/2 activated by the beta-arrestin scaffold is largely excluded from the nucleus and confined to cytoplasmic locations such as endocytic vesicles, also called beta-arrestin signalosomes. Recruits c-Src/SRC to ADRB2 resulting in ERK activation. GPCRs for which the beta-arrestin-mediated signaling relies on both ARRB1 and ARRB2 (codependent regulation) include ADRB2, F2RL1 and PTH1R. For some GPCRs the beta-arrestin-mediated signaling relies on either ARRB1 or ARRB2 and is inhibited by the other respective beta-arrestin form (reciprocal regulation). Inhibits ERK1/2 signaling in AGTR1- and AVPR2-mediated activation (reciprocal regulation). Is required for SP-stimulated endocytosis of NK1R and recruits c-Src/SRC to internalized NK1R resulting in ERK1/2 activation, which is required for the antiapoptotic effects of SP. Is involved in proteinase-activated F2RL1-mediated ERK activity. Acts as signaling scaffold for the AKT1 pathway. Is involved in alpha-thrombin-stimulated AKT1 signaling. Is involved in IGF1-stimulated AKT1 signaling leading to increased protection from apoptosis. Involved in activation of the p38 MAPK signaling pathway and in actin bundle formation. Involved in F2RL1-mediated cytoskeletal rearrangement and chemotaxis. Involved in AGTR1-mediated stress fiber formation by acting together with GNAQ to activate RHOA. Appears to function as signaling scaffold involved in regulation of MIP-1-beta-stimulated CCR5-dependent chemotaxis. Involved in attenuation of NF-kappa-B-dependent transcription in response to GPCR or cytokine stimulation by interacting with and stabilizing CHUK. May serve as nuclear messenger for GPCRs. Involved in OPRD1-stimulated transcriptional regulation by translocating to CDKN1B and FOS promoter regions and recruiting EP300 resulting in acetylation of histone H4. Involved in regulation of LEF1 transcriptional activity via interaction with DVL1 and/or DVL2 Also involved in regulation of receptors others than GPCRs. Involved in Toll-like receptor and IL-1 receptor signaling through the interaction with TRAF6 which prevents TRAF6 autoubiquitination and oligomerization required for activation of NF-kappa-B and JUN. Binds phosphoinositides. Binds inositolhexakisphosphate (InsP6).
配列類似性

Belongs to the arrestin family.
ドメイン

The [DE]-X(1,2)-F-X-X-[FL]-X-X-X-R motif mediates interaction the AP-2 complex subunit AP2B1 (By similarity). Binding to phosphorylated GPCRs induces a conformationanl change that exposes the motif to the surface.
The N-terminus binds InsP6 with low affinity.
The C-terminus binds InsP6 with high affinity.
翻訳後修飾

Constitutively phosphorylated at Ser-412 in the cytoplasm. At the plasma membrane, is rapidly dephosphorylated, a process that is required for clathrin binding and ADRB2 endocytosis but not for ADRB2 binding and desensitization. Once internalized, is rephosphorylated.
The ubiquitination status appears to regulate the formation and trafficking of beta-arrestin-GPCR complexes and signaling. Ubiquitination appears to occur GPCR-specific. Ubiquitinated by MDM2; the ubiquitination is required for rapid internalization of ADRB2. Deubiquitinated by USP33; the deubiquitination leads to a dissociation of the beta-arrestin-GPCR complex. Stimulation of a class A GPCR, such as ADRB2, induces transient ubiquitination and subsequently promotes association with USP33.
細胞内局在

Cytoplasm. Nucleus. Cell membrane. Membrane > clathrin-coated pit. Cell projection > pseudopodium. Cytoplasmic vesicle. Translocates to the plasma membrane and colocalizes with antagonist-stimulated GPCRs. The monomeric form is predominantly located in the nucleus. The oligomeric form is located in the cytoplasm. Translocates to the nucleus upon stimulation of OPRD1.

Question

I did Immunocytochemistry with Ab32099 antibody from Abcam and control antibody which already tested with purified beta-arrestin2 protein and used for several publications before. The cell type that I used is beta-arrestin1/2 double knockout Mouse Embryonic Fibroblasts ( DKO MEFs). First, I transfected beta-arrestin1 mammalian expression vector in DKO MEFs in 60 mm culture dish and let them express for 48 hr. After that, I split cells into 4 well-chamber slide coated with poly-L-Lysine and fibronectin and let them stabilize for additional 24hr. Cells were fixed with 4% paraformaldehyde for 15 min at room temperature (RT) and blocked with 3% BSA in PBS for 1 hr at RT. First try of staining, I incubated samples with ab32099 antibody for 1hr at RT as described in datasheet and AlexaFluor488-conjugated anti-rabbit secondary antibody was incubated for 1hr at R.T. After that, I looked at my slides under confocal microscope, but I could not see any staining with ab32099 even though I could find stained cells with control beta-arrestin1 antibody. For second try of staining, I tried a longer incubation with ab32099 antibody for 2 days at 4 degree and followed same way like first try for secondary antibody. But still I could not see any stanining with ab32099 and I attached the representative image file for your information. I am so glad that Abcam has Abpromise guarantee and the product that I bought is covered by Abpromise guarantee.

Question

I purchased anti-beta Arrestin1 antibody (ab32099) from Abcam on Oct-18-2012 because according to the datasheet, this antibody is working for immunocytochemistry. I used beta Arrestin1/2 knockout MEFs cell line for my experiment. It mean there is no endogenous beta Arrestin1/2 that could be give us any background staining with antibody. I transiently transfected Arrestin DKO MEFs with beta-Arrestin1 and followed the method for Immunocytochemistry that described in antibody datasheet. I attach the images from control beta-Arrestin antibody and Abcam beta-Arrestin antibody. As you can check, control arrestin antibody gave us the staining, but Abcam antibody could not even though I used exactly same transfected cell sample.

Question

We ordered the anti- beta-arrestin 1 and anti- beta-arrestin 2 antibodies from your company recently. The information is as below: Rabbit monoclonal[E274] to beta-arrestin 1 (ab32099) Lot# GR37458-5 Goat polyclonal (ab31294) for the beta-arrestin 2 Lot#GR77572-1 The beta-arrestin1 antibodies works by showing that knockdown of beta-arrestin1 decrease the proper size band. But the anti-beta-arrestin2 is not working (no bands showed up even after overexpression of beta-arrestin2 protein in the cells). I am wondering if you might kindly send us some positive control for beta-arrestin 2 or a new batch of antibody? Thanks & I am looking forward to your reply!

Question

I used western blot to test the heart fibroblast beta-arrestins expression. The normal RIPA buffer was used to lysis the cells (which was also added with PMSF, Protein kinase inhibitor cocktail). After blotting 30 ug of the protein onto PVDF membrane, the membrane was developed for the western. (5% BSA was used as a blocking buffer and antibody dilution buffer; 1st antibody was developing at 4 degree overnight (1:500 dilution), and 2nd antibody was developing at RT for 2 hours). But finally I could not get any bands for the beta-arrestin2 antibody in the proper size site. Could you kindly send us the positive control to help us to find out if the antibody is working or not. Or we need change to another batch or different Cat# antibody?

Dear Sir/Madam, We ordered the anti- beta-arrestin 1 and anti- beta-arrestin 2 antibodies from your company recently. The information is as below: Rabbit monoclonal[E274] to beta-arrestin 1 (ab32099) Lot# GR37458-5 Goat polyclonal (ab31294) for the beta-arrestin 2 Lot#GR77572-1 The beta-arrestin1 antibodies works by showing that knockdown of beta-arrestin1 decrease the proper size band. But the anti-beta-arrestin2 is not working (no bands showed up even after overexpression of beta-arrestin2 protein in the cells). I am wondering if you might kindly send us some positive control for beta-arrestin 2 or a new batch of antibody? Thanks & I am looking forward to your reply!
