HHV-8 ORF74 is a gene encoded by Human Herpesvirus 8 (HHV-8), also known as Kaposi's Sarcoma-associated Herpesvirus (KSHV). ORF74 is notable for encoding a G protein-coupled receptor (GPCR) known as vGPCR or KSHV-GPCR. This viral GPCR is homologous to human chemokine receptors and is constitutively active, meaning it can signal in the absence of ligand binding. The constitutive activity of ORF74 leads to the continuous activation of downstream signaling pathways, including those involving MAPK/ERK and NF-kappaB, which promote cell proliferation, survival, and angiogenesis. This activity is implicated in the pathogenesis of Kaposi's Sarcoma, as well as other HHV-8-associated diseases such as primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD). The oncogenic potential of ORF74 makes it a significant target for research into therapeutic interventions aimed at treating HHV-8-related malignancies. Understanding the mechanisms by which ORF74 contributes to viral oncogenesis and immune evasion is critical for the development of targeted therapies that can mitigate the effects of this viral gene product.
