This domain is found centrally located in Receptor binding protein from Lactococcus phage p2 (RBP, also known as Gp18) and similar proteins from closely related lactococcal phages. RBP shows three domains: the N-terminal shoulder domain (Pfam:PF20747), which is attached to the phage, the neck domain (this entry) and the C -terminal receptor-recognition head domain (Pfam:PF08931). The central domain folds into four beta-strands, which interlace with the beta-strands of two other subunits to form an equilateral triangular prism around the three-fold axis of a triple-stranded beta-helix [1,2].

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 [1]. This family now includes DUF1914. Family Baseplate, Pfam:PF16774, is the ORF15 or shoulder component of the base-plate complex.	Domain

This domain is found at the N-terminal end of Distal tail protein from Lactococcus phage p2 (Dit) and similar sequences predominantly found in Siphoviridae and bacterial prophages from Lactobacillales. Dit has a structural role and forms the distal part of the tail. It is organised into two domains, a ring domain that shows a split (this entry) barrel-like fold and a C-terminal galectin domain. Consecutive Dit N-terminal domains form a tight ring with two layers of beta-strands. This ring frames a channel sufficiently large for dsDNA passage [1,2].	Domain
