Phospho-CrkL (Tyr207) (G4) rabbit mAb
Product Overview
Description
CrkL (v-Crk sarcoma virus CT10 oncogene-like protein) is an adaptor protein composed of one Src Homology 2 (SH2) and two Src Homology 3 (SH3) domains separated by flexible linker sequences that act as building blocks to assemble multiprotein complexes (1). The Crk adaptor proteins (Crk and CrkL) constitute an integral part of a network of essential signal transduction pathways in humans and other organisms that act as major convergence points in tyrosine kinase signaling. CRKL is required for the normal development of multiple tissues that rely on fibroblast growth factor 8 (FGF8). Phosphorylation of Crk on Tyr 221 or CrkL on Tyr 207 causes intramolecular binding of the linker region to the SH2 domain, sequestering the SH2 and SH3N and preventing them from binding target proteins (2,3). Mounting evidence indicates that dysregulation of Crk proteins is associated with human diseases, including cancer and susceptibility to pathogen infections.

Western blot of E10.5 mouse wild-type (+/+) or Crkl knock out (-/-) whole embryos. The red channel was stained using a β-actin loading control and the green channel was stained using 1:500 dilution of Phospho-CrkL (Tyr207) antibody CrkLY207-G4 Cat. #2091. Phospho CrkL antibody staining is absent in the knock out lysate.
