CC -!- FUNCTION: Probable head completion protein that exhibits an open
CC central channel for viral DNA ejection. Part of the head-tail connector
CC by binding to the portal protein and to the head completion protein 2.
CC Plays a role in morphogenesis of the virion capsid after genome
CC packaging. {ECO:0000250|UniProtKB:D3WAC7}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:D3WAC7}. Note=Part
CC of the connector between the portal and the tail.
CC {ECO:0000250|UniProtKB:D3WAC7}.
CC -!- SIMILARITY: Belongs to the skunalikevirus head completion protein 1
CC family. {ECO:0000305}.
