Inner tegument protein

UniProtKB accession:  P10221

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays an essential role in cytoplasmic secondary envelopment during viral egress. Interacts with the capsid via the large tegument protein/LTP and participates in its transport to the host trans-Golgi network (TGN) where secondary envelopment occurs. Modulates tegumentation and capsid accumulation at the viral assembly complex (By similarity). Plays a role in microtubule-based retrograde axonal transport to promote neuroinvasion (PubMed:29216315). Also plays a role in the inhibition of host immune response by acting as a viral deamidase (PubMed:27866900). Deamidates host RIGI on two asparagines which becomes unable to sense viral dsRNA. In turn, its ability to trigger antiviral immune response and restrict viral replication is inhibited (PubMed:27866900). Deamidates also a critical asparagine on host CGAS which abolishes cGAMP synthesis and downstream innate immune activation (PubMed:30092200).
