Probable Vpr-like protein

Gene
N/A
Organism
Feline immunodeficiency virus (strain San Diego) (FIV)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein predictedi

Functioni

Seems to function as a Vpr-like protein, since it mediates host cell cycle arrest in G2 phase. Cell cycle arrest creates a favorable environment for maximizing viral expression and production.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.

Caution

Was first thought to be the equivalent of lentiviral Tat protein.Curated
PubMed:1323707 sequence does not seem to originate from isolate Petaluma as described, but rather from the strain San Diego.Curated
