CrkL: Products

CrkL is a widely-expressed 39 kD adaptor protein that belongs to the Crk protein family and is abundantly expressed in cells of hematopoetic origin. Through its SH2 and SH3 domains CrkL initiates interactions with numerous downstream proteins such as CBL, Cas, Paxillin, C3G, SOS, PI3K, c-Abl and BCR/Abl. It is involved in processes such as adhesion, migration and immune responses. Furthermore, CrkL plays an essential role in Chronic Myelogenous Leukemia and is constitutively phosphorylated by the Bcr-Abl kinase in this disease.
