Protein
G-protein coupled receptor BILF1
Organism
Epstein-Barr virus (strain B95-8)
Function
Constitutively active G protein-coupled receptor that plays a role in the modulation of host immunity. As a consequence of its constitutive activity, mediates host CXCR4 inhibition. Enhances degradation of host major histocompatibility complex class I antigens via lysosomes. Targets also newly synthesized MHC-I/peptide complexes en route to the host cell surface. Inhibits the host EIF2AK2/PKR phosphorylation.
Similarity
Belongs to the Epstein-Barr virus BILF1 protein family.
