MHC class I polypeptide–related sequence B

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.
