RAET1G

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