精製度Immunogen affinity purified
特記事項（精製）Purified from rabbit serum by epitope specific chromatography. The antibody has been negatively pre-adsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated PYK 2. The final product is generated by affinity chromatography using a PYK 2-derived peptide that is phosphorylated at tyrosine 402.
Our Abpromise guarantee covers the use of ab4800 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/1000. Predicted molecular weight: 116 kDa. Can be blocked with PYK2 peptide - phospho Y402 (phospho and non-phospho pair) or CEF whole cell lysate, positive / negative for PYK 2 (pair).
ICC/IF: Use at an assay dependent dilution from (PubMed:17325207).
Not tested in other applications.

機能Involved in calcium induced regulation of ion channel and activation of the map kinase signaling pathway. May represent an important signaling intermediate between neuropeptide activated receptors or neurotransmitters that increase calcium flux and the downstream signals that regulate neuronal activity. Interacts with the SH2 domain of Grb2. May phosphorylate the voltage-gated potassium channel protein Kv1.2. Its activation is highly correlated with the stimulation of c-Jun N-terminal kinase activity. Involved in osmotic stress-dependent SNCA 'Tyr-125' phosphorylation. In concert with SRC, plays an important role in osteoclastic bone resorption. Both the formation of a SRC-PTK2B complex, and SRC kinase activity are necessary for this function. The Tyr-402 phosphorylated form serves as a docking site for SRC and is important for the organization of the osteoclast actin cytoskeleton and attachment sites and for bone resorption.
組織特異性Most abundant in the brain, with highest levels in amygdala and hippocampus. Low levels in kidney. Also expressed in spleen and lymphocytes.
配列類似性Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
Contains 1 FERM domain.
Contains 1 protein kinase domain.
翻訳後修飾Phosphorylated on tyrosine residues in response to various stimuli that elevate the intracellular calcium concentration, as well as by PKC activation. Recruitment by nephrocystin to cell matrix adhesions initiates Tyr-402 phosphorylation. In monocytes, adherence to substrata is required for tyrosine phosphorylation and kinase activation. Angiotensin II, thapsigargin and L-alpha-lysophosphatidic acid (LPA) also induce autophosphorylation and increase kinase activity.
細胞内局在Cytoplasm. Cell membrane. Interaction with nephrocystin induces the membrane-association of the kinase.

Peptide Competition: Extracts prepared from CEF cells expressing Pyk2 and plated on fibronectin were resolved by SDS-PAGE on a 10% Tris glycine gel. The proteins were then transferred to nitrocellulose. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4oC, then were incubated with 0.50
µg/mL ab4800 antibody, following prior incubation with: no peptide (1), the non-phosphopeptide corresponding to phosphopeptide immunogen (2), a generic phosphotyrosine containing peptide (3), the phosphopeptide corresponding to tyrosine 397 on FAK (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar method. The data show that only the phosphopeptide corresponding to this site blocks the antibody signal, therefore demonstrating the specificity of ab4800 antibody for this phosphorylated residue.

Figure shows Pyk2 staining: Normal mouse mammary (NmuMG) cells were treated with TGFbeta and then grown to confluence, fixed and permeabilized. ab4800 was identified using a selective PSSA followed by incubation with a Cy3-conjugated anti-rabbit secondary antibody (red). F actin was visualized with Oregon Green-conjugated phalloiden (green) and paxillin staining is indicated in blue. The merged image indicates colocalization (purple) of ab4800, F-actin and paxillin in focal adhesion structures.
