FUNCTION

MHC class I polypeptide–related sequence A (MICA) is a highly polymorphic cell surface glycoprotein encoded by the MICA gene located within MHC locus. MICA is related to MHC class I and it has similar domain structure, however, it is not associated with β2-microglobulin nor binds peptides as conventional MHC class I molecules do. MICA rather functions as a stress-induced ligand (as a danger signal) for integral membrane protein receptor NKG2D ("natural-killer group 2, member D"). MICA is broadly recognized by NK cells, γδ T cells, and CD8+ αβ T cells which carry NKG2D receptor on their cell surface and which are activated via this interaction. MHC class I polypeptide-related sequence B (MICB) is a protein that is encoded by the MICB gene located within MHC locus. MICB is related to MHC class I and has similar domain structure, which is made up of external α1α2α3 domain, transmembrane segment and C-terminal cytoplasmic tail. MICB is a stress-induced ligand for NKG2D receptor. The heat shock stress pathway is involved in the regulation of MICB expression as transcription of MICB is regulated by promoter heat shock element.
