Description
Product Characteristics: SLP65 / BLNK (SH2 domain-containing leukocyte-specific phosphoprotein of 65 kDa, B cell linker protein), also known as BASH, is an adaptor protein that plays key role in B cell activation initiated by cross-linking the B cell receptor (BCR). Phosphorylated by Syk tyrosine kinase, SLP65 serves as a scaffold for Btk tyrosine kinase, Vav1 guanine nucleotide exchange factor, phospholipase C gamma2, as well as Grb2 and Nck adaptor proteins, thus represents a central linker protein that bridges the BCR-associated kinases with a multitude of signaling pathways.
Target Information: This gene encodes a cytoplasmic linker or adaptor protein that plays a critical role in B cell development. This protein bridges B cell receptor-associated kinase activation with downstream signaling pathways, thereby affecting various biological functions. The phosphorylation of five tyrosine residues is necessary for this protein to nucleate distinct signaling effectors following B cell receptor activation. Mutations in this gene cause hypoglobulinemia and absent B cells, a disease in which the pro- to pre-B-cell transition is developmentally blocked. Deficiency in this protein has also been shown in some cases of pre-B acute lymphoblastic leukemia. Alternatively spliced transcript variants have been found for this gene.
