CRK Proto-Oncogene, Adaptor Protein (CRK) Antibody

Background

Proto-oncogene c-Crk (CRK) is an adaptor protein that plays a critical role in various cellular processes, including signal transduction, cellular migration, and proliferation. It does not have enzymatic activity but acts by interacting with other proteins via its SH2 and SH3 domains. These interactions are crucial for the transmission of signals from receptor tyrosine kinases (RTKs) and other cellular receptors, which control processes like cell growth and differentiation. CRK is involved in many pathways, including those related to cell adhesion, cytoskeletal rearrangement, and survival. Its involvement in regulating these processes makes it a key player in cancer biology, where it can function as an oncogene when dysregulated.
