High-affinity ELR+ CXC chemokines display balanced G protein-, GRK- and β-arrestin-associated transducer engagement at the viral G protein-coupled receptor ORF74
Open reading frame 74 (ORF74) is the single G protein-coupled receptor (GPCR) encoded in the genome of Kaposi’s sarcoma-associated herpesvirus (KSHV). Due to its high constitutive activity and broad chemokine binding profile, ORF74 contributes to KSHV-associated diseases through autocrine and paracrine mechanisms tha...
