Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Phospho-FAK (Tyr397) (D20B1) Rabbit mAb detects FAK protein only when phosphorylated at Tyr397. This antibody may cross-react with overexpressed tyrosine phosphorylated proteins such as EGFR.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr397 of human FAK protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from A549 cells, untreated or treated with calf intestinal phosphatase (CIP), using Phospho-FAK (Tyr397) (D20B1) Rabbit mAb (upper) and FAK Antibody #3285 (lower).

Background

Focal adhesion kinase (FAK) is a widely expressed cytoplasmic protein tyrosine kinase involved in integrin-mediated signal transduction. It plays an important role in the control of several biological processes, including cell spreading, migration, and survival (1). Activation of FAK by integrin clustering leads to autophosphorylation at Tyr397, which is a binding site for the Src family kinases PI3K and PLCγ (2-5). Recruitment of Src family kinases results in the phosphorylation of Tyr407, Tyr576, and Tyr577 in the catalytic domain, and Tyr871 and Tyr925 in the carboxy-terminal region of FAK (6,7).
