MAFA

MAFA (Mast cell function-associated antigen) is a , first identified on the surface of rat mucosal-type mast cells of the . More recently, human and mouse homologues of MAFA have been discovered yet also (or only) expressed by NK and T-cells.^[1]

The intracellular domain of MAFA contains a single immunoreceptor tyrosine-based inhibitory motif (ITIM), which classifies MAFA as a member of an superfamily. The inhibitory capacity of MAFA is best defined in mast cells, where MAFA keeps in check the antigen-induced (i.e. Fc epsilon RI-induced) secretion of inflammatory mediators.^{[citation needed]}
