| Enzyme Function | FUNCTION: Envelope protein which participates in virus morphogenesis. Needed for an early step in viral crescent membrane formation by interacting with D13 scaffold protein. Its interaction with D13 scaffold protein leads to the formation of rigid, crescent-shaped membranes that assemble around the cytoplasmic virus factory. Membrane anchor for the protein A27. A17-A27 virus envelope protein might be involved in fusion or attachment, and can further associate to A26 (By similarity). {ECO:0000250}. |

| Subcellular Location | SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}. Note=The 23 kDa precursor is associated with immature virions (IV) and the final 21 kDa form is present in mature virions (MV). {ECO:0000250}. |
| Modified Residue | MOD_RES 203; /note=Phosphotyrosine; /evidence=ECO:0000250 |
| Post Translational Modification | PTM: The 23 kDa precursor is cleaved into a final 21 kDa form by the I7 protease during virus maturation. {ECO:0000250}.; PTM: Phosphorylated on tyrosine and threonine. Its phosphorylation state is regulated by the F10 kinase and the H1 phosphatase (By similarity). Phosphorylation by F10 kinase seems to be required to form the membranes associated with IV (By similarity). {ECO:0000250}.; PTM: Not glycosylated. {ECO:0000250}. |
