Sujet
NTAL (Non-T cell activation linker), also known as LAB (Linker for activation of B cells), is a 30 kDa double-palmitoylated transmembrane adaptor protein expressed by B cells, NK cells, mast cells and macrophages. It is a negative regulator of early stages of BCR-dependent B cell signaling and serves as a negative regulator also in mast cells. However, in mast cells, NTAL also contributes to some activation processes, partially overlapping with LAT function.Synonyms: HSPC046, LAB, LLinker for activation of B-cells, Linker for activation of T-cells family member 2, Membrane-associated adapter molecule, NTAL, Non-T-cell activation linker, WBS15, WBSCR5, Williams-Beuren syndrome chromosomal region 15 protein
