Protein

ICP47 protein

Gene

US12

Organism
Human herpesvirus 1 (strain 17) (HHV-1) (Human herpes simplex virus 1)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Binds specifically to transporters associated with antigen processing (TAP), thereby blocking peptide-binding and translocation by TAP as well as subsequent loading of peptides onto MHC class I molecules in the endoplasmic reticulum. In consequence, infected cells are masked for immune recognition by cytotoxic T-lymphocytes.3 Publications
