Protein

Neurovirulence factor ICP34.5

Gene

RL1

Organism
Human herpesvirus 1 (strain 17) (HHV-1) (Human herpes simplex virus 1)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Contributes to HSV resistance to the antiviral effects of alpha/beta interferon. Recruits the serine/threonine-protein phosphatase PPP1CA/PP1-alpha to dephosphorylate the translation initiation factor eIF-2A, thereby couteracting the host shutoff of protein synthesis involving double-stranded RNA-dependent protein kinase EIF2AK2/PKR. Also down-modulates the host MHC class II proteins cell surface expression. Acts as a neurovirulence factor that has a profound effect on the growth of the virus in central nervous system tissue, probably through its ability to maintain an environment favorable for viral replication (By similarity).By similarity

Subcellular locationi

Host cytoplasm By similarity. Host nucleushost nucleolus By similarity. Virion By similarity
Note: At early times in infection, colocalizes with PCNA and replication proteins in cell nuclei, before accumulating in the cytoplasm by 8 to 12 hours post-infection. The effects on the host cell are probably mediated by de novo-synthesized ICP34.5, the virion-derived population being either non-functional or present in very low amounts.

Interactioni

Subunit structurei

Interacts with human PPP1CA to form a high-molecular-weight complex that dephosphorylates eIF2-alpha (By similarity). Binds to proliferating cell nuclear antigen (PCNA), which may release host cells from growth arrest and facilitate viral replication.By similarity1 Publication

Miscellaneousi

Miscellaneous

ICP34.5 is detected as early as 3 hpi prior to viral replication but reaches maximal levels late in infection. ICP34.5 gene is therefore classified as gamma-1 or leaky late gene.
The phosphatase activity of the ICP34.5-PP1 complex toward EIF2S1 is specifically inhibited by Salubrinal, which inhibits viral replication.By similarity
