Related Product Information for
anti-BLNK antibody
BLNK (B cell linker protein) is an adaptor molecule that plays key roles from B cell activation through B cell antigen receptor (BCR) engagent. BLNK acts on the inferface between BCR-associated Syk and the downstream signaling cascade (1,2). BLNK has multiple SH2 binding motifs (YXXP) at its N-terminus and an SH2 domain at its C-terminus. After BCR ligation, BLNK is phosphorylated by Syk on its multiple YXXP motifs including Tyr72, Tyr84, Tyr96 and Tyr178 (1). The phosphorylation on these motifs provides docking sites for signaling molecules such as Btk, PLCgamma and Vav. They bind to BLNK through their SH2 domains and cooperatively activate downstream signaling (3,4). BLNK can also interact with phosphorylated targets such as HPK1 through its SH2 domain to activate the pathway (5).

NCBI Summary for BLNK
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 encoding different isoforms have been found for this gene. [provided by RefSeq]
UniProt Comments for BLNK
BLNK iso3: an adaptor protein that bridges the B-cell receptor-associated kinases (BCR) with a multitude of signaling pathways, regulating biologic outcomes of B-cell function and development. Plays an important role in BCR-mediated PLCG1 activation and Ca(2 ) mobilization. Does not seem to be not required for pre-BCR-mediated activation of MAP kinase and phosphatidyl-inositol 3 (PI3) kinase signaling. Plays a critical role in orchestrating the pro-B cell to pre-B cell transition. Following BCR activation, phosphorylated on tyrosine residues by SYK and LYN. When phosphorylated, serves as a scaffold to assemble downstream targets of antigen activation, including PLCG1, VAV1, GRB2 and NCK1. Its phosphorylation is required for both Ca(2 ) and MAPK signaling pathways. Defects in BLNK are the cause of hypoglobulinemia and absent B-cells.It has tumor supressor activity that is lost in many cases of childhood pre-B acute lymphoblastic leukemia (ALL). Two alternatively spliced isoforms have been described; these are differentially involved in activation and apoptosis of B lymphocytes.
