IQGAP1 Antibody

Western blot shows lysates of HUVEC human umbilical vein endothelial cells, HepG2 human hepatocellular carcinoma cell line, U937 human histiocytic lymphoma cell line, and MRC-5 human embryonic lung fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Human IQGAP1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5069) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for IQGAP1 at approximately 195 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

IQGAP1 (IQ motif with Ras GAP-related domain 1) is a 195 kDa member of the IQGAP family of proteins. It serves as an effector protein for Rho family members, and regulates actin polymerization. Human IQGAP1 is 1657 amino acids (aa) in length. It contains one actin-binding CH domain (aa 45‑159), a Pro-binding WWP region (aa 685‑711), four consecutive calmodulin-binding IQ motifs (aa 745‑864), and a noncatalytic Ras-GAP domain (aa 1004‑1237). Amino acids 763‑863 mediate homodimerization. There are at least three IQGAP1 splice variants. One shows a two Lys substitution for aa 270‑1657, a second shows a ten Lys substitution for aa 299‑1657, and a third shows a three Lys substitution for aa 941‑1657.
