CC   -!- FUNCTION: Protein of the infection vertex complex, which increases the
CC       vertex stability. Anchors the vertex structure to the viral membrane.
CC       Essential for viral infectivity. {ECO:0000269|PubMed:15331712}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000305}. Note=Part of the capsid inner membrane.
CC       {ECO:0000305}.
