UniProt functional annotation for E3TMG9

UniProt code: E3TMG9.

Organism: Saffold virus (SafV) (Human TMEV-like virus-Saffold).
Taxonomy: Viruses; Riboviria; Orthornavirae; Pisuviricota; Pisoniviricetes; Picornavirales; Picornaviridae; Cardiovirus.
 
Function: Affects membrane integrity and causes an increase in membrane permeability. {ECO:0000256|ARBA:ARBA00004017}.
 
Function: Forms a primer, VPg-pU, which is utilized by the polymerase for the initiation of RNA chains. {ECO:0000256|ARBA:ARBA00002520}.
 
Function: Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3. Together they form an icosahedral capsid composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms.VP4 lies on the inner surface of the protein shell formed by VP1, VP2 and VP3. All the three latter proteins contain a beta-sheet structure called beta-barrel jelly roll. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. {ECO:0000256|ARBA:ARBA00002469}.
 
Function: Serves as membrane anchor via its hydrophobic domain. {ECO:0000256|ARBA:ARBA00003704}.
 
Function: VP0 precursor is a component of immature procapsids. {ECO:0000256|ARBA:ARBA00002982}.
