Target Details for B-Cell Linker

Target: B-Cell Linker (BLNK)

Alternative Name: BLNK

Background: B cell activation is initiated by crosslinking the B cell receptor, which leads to activation of non-receptor protein tyrosine kinases (PTK), including Btk, Syk, and three Src kinases, Fyn, Lyn, and Blk. Activated PTKs then phosphorylate multiple cellular proteins involved in B lymphocyte signaling. Syk is responsible for the tyrosine phosphorylation of B cell linker protein (BLNK), a member of the SLP-76 family of adapter proteins. Phosphorylation of human BLNK at tyrosines 84, 178, and 189 (Y84, Y178, and Y189) creates docking sites for PLCg2, leading to the activation of downstream signaling pathways. The 2B11 monoclonal antibody recognizes BLNK, regardless of phosphorylation status. A fusion protein representing amino acids 4-205 of human BLNK was used as the immunogen. BLNK is expressed as two phosphoproteins migrating at 68 and 70 kDa in SDS/PAGE that represent alternatively spliced forms of human BLNK.
