MeSH note : HCMV - human cytomegalovirus; a type I membrane protein, prevents maturation of class
I major histocompatibility complex (MHC) molecules by retaining them in the endoplasmic
reticulum (ER) and thus helps inhibit antigen presentation to cytotoxic T cells; bind
to class I MHC molecules in a transient fashion but retain them very efficiently in
the ENDOPLASMIC RETICULUM; has been sequenced;
