RAET1G
From Wikipedia, the free encyclopedia
Retinoic acid early transcript 1G (RAET1G) is a cell surface glycoprotein encoded by RAET1G gene located on chromosome 6.[1] RAET1G is related to MHC class I molecules, but its gene maps outside the MHC locus.[1] RAET1G is composed of an external α1α2 domain, a transmembrane segment, and C-terminal cytoplasmic tail.[1][2] RAET1E functions as a stress-induced ligand for NKG2D receptors.[2]
