CC   -!- FUNCTION: Forms the distal part of the tail. Self-associates as two
CC       rings organized back to back, with a central channel allowing DNA
CC       ejection. {ECO:0000250|UniProtKB:D3WAD3}.
CC   -!- SUBUNIT: Homohexamer. Interacts with the receptor binding protein.
CC       {ECO:0000250|UniProtKB:D3WAD3}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:D3WAD3}. Note=Part
CC       of the tail. {ECO:0000250|UniProtKB:D3WAD3}.
CC   -!- SIMILARITY: Belongs to the skunalikevirus distal tail protein family.
CC       {ECO:0000305}.
