Scientific Data Images for Human Phospho-FAK (S843) Antibody
Detection of Human Phospho-FAK (S843) by Western Blot.
Western blot shows lysates of HUVEC human umbilical vein endothelial cells untreated (-) or treated (+) with 1 mM Pervanadate (PV) 5 minutes and 300 U/mL CIP for 1 hour. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Phospho-FAK (S843) Monoclonal Antibody (Catalog # MAB7298) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Phospho-FAK (S843) at approximately 125 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human Phospho-FAK (S843) Antibody

Background: FAK
Focal adhesion kinase 1 (FAK) is a ubiquitously expressed non-receptor protein tyrosine kinase that is concentrated in the focal adhesions that form between cells growing in the presence of extracellular matrix constituents. This cellular localization is directed by a "Focal Adhesion Targeting" (FAT) sequence, a 125 amino acid sequence at the C-terminus. FAK plays an important role in migration, cell spreading, differentiation, cytoskeleton protein phosphorylation, apoptosis and acceleration of the G1 to S phase transition of the cell cycle. It associates with several different signaling proteins such as Src-family PTKs, p130Cas, Shc, Grb2, PI 3-kinase, and paxillin. This enables FAK to function within a network of integrin-stimulated signaling pathways leading to the activation of targets such as the ERK and JNK/mitogen-activated protein kinase pathways. FAK is also linked to oncogenes at biochemical and functional levels. Increased expression and/or activity of FAK in various tumors has been correlated with enhanced migration and invasiveness of human tumor cells in addition to promoting increased cell proliferation.
