description: Caudo_bapla_RBP is a family of proteins expressed from ORF18 of the Lactococcus P2-like phage.
  This is one of three protein domains, shoulders, neck, and head, that form the phage tail base-plate.
  In the overall structure this head domain exists as six trimers, and is necessary for specific recognition
  of the receptors at the host cell surface. Siphoviridae are the P2-like Caudovirales of Lactococcus
  [[cite:PUB00054437]]. This family now includes DUF1914. Family Baseplate, [pfam:PF16774], is the ORF15
  or shoulder component of the base-plate complex.
