|IHC-P||1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
機能Binds to activated CDC42 but does not stimulate its GTPase activity. It associates with calmodulin. Could serve as an assembly scaffold for the organization of a multimolecular complex that would interface incoming signals to the reorganization of the actin cytoskeleton at the plasma membrane. May promote neurite outgrowth.
組織特異性Expressed in the placenta, lung, and kidney. A lower level expression is seen in the heart, liver, skeletal muscle and pancreas.
配列類似性Contains 1 CH (calponin-homology) domain.
Contains 4 IQ domains.
Contains 1 Ras-GAP domain.
Contains 1 WW domain.
ドメインRegions C1 and C2 can either interact with nucleotide-free CDC42, or interact together, depending on the phosphorylation state of Ser-1443. When Ser-1443 is not phosphorylated, C1 and C2 interact, which prevents binding of nucleotide-free CDC42 and promotes binding of GTP-bound CDC42. Phosphorylation of Ser-1443 prevents interaction between C1 and C2, which opens the structure of the C-terminus and allows binding and sequestration of nucleotide-free CDC42 on both C1 and C2.
翻訳後修飾Phosphorylation of Ser-1443 by PKC prevents interaction between C1 and C2, allowing binding of nucleotide-free CDC42. Ser-1443 phosphorylation enhances the ability to promote neurite outgrowth.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labelling IQGAP1 with ab86064 at 1/1000 (0.2µg/ml) and 1/200 (1µg/ml). Detection: DAB and a DyLight® 594-conjugated goat anti-rabbit IgG (H+L) (1/100).
Detection of IQGAP1 by Western Blot of Immunprecipitate.
ab86064 at 0.4µg/ml staining IQGAP1 in HeLa whole cell lysate immunoprecipitated using ab86064 at 3µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
Detection: Chemiluminescence with exposure time of 10 seconds.
ab86064 staining IQGAP1 in human pacreatic islets by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
Tissue was fixed in paraformaldehyde and a heat mediated antigen retrieval step was performed using citrate. Samples were then blocked with 5% serum for 1 hour at 20°C and then incubated with ab86064 at a 1/100 dilution for 8 hours at 4°C. The secondary used was a biotin conjugated goat anti-rabbit polyclonal used at a 1/1000 dilution.
ab86064 stained SKNSH cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab86064 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in Methanol fixed (100%, 5min) SKNSH cells at 1ug/ml.
