US11

Organism
Human cytomegalovirus (strain Merlin) (HHV-5) (Human herpesvirus 5)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Participates in the inhibition of the host immune response. Redirects newly synthesized MHC class I heavy chains via the SEC61 translocon to the cytosol where they undergo proteasome-dependent destruction. In consequence, infected cells are masked for immune recognition by cytotoxic T-lymphocytes (By similarity).By similarity

Post-translational modificationi

N-glycosylated.By similarity
A fraction of newly synthesized molecules retain the signal peptide after the N-linked glycan has been attached and translation of the polypeptide has been completed. Delayed cleavage of the signal peptide is determined by the first four residues, as well as by the transmembrane region (By similarity).By similarity
