B Lymphocyte Kinase Recombinant Protein

Tyrosine-Protein Kinase Blk, B Lymphocyte Kinase, p55-Blk, BLK

This recombinant protein can be used for biological assays. For research use only.

Tyrosine-Protein Kinase Blk (BLK) contains one protein kinase domain, one SH2 domain and one SH3 domain. BLK is a non-receptor tyrosine kinase, which is involved in B-lymphocyte development, differentiation and signaling. B-cell receptor (BCR) signaling requires a tight regulation of several protein tyrosine kinases and phosphatases, and associated coreceptors. Signaling through BLK plays an important role in transmitting signals through surface immunoglobulines and supports the pro-B to pre-B transition, as well as the signaling for growth arrest and apoptosis downstream of B-cell receptor. Defects in BLK are a cause of maturity-onset diabetes of the young type 11 (MODY11).

Supplied as a 0.2 um filtered solution of 20mM Tris, 500mM NaCl, 1mM DTT, pH 7.4. It is not recommended to reconstitute to a concentration less than 100 ug/ml.
