CC -!- FUNCTION: Intermediate/inner baseplate protein (PubMed:27193680,
CC PubMed:15315755). The gp25-(gp6)2-gp7 module is involved in sheath
CC contraction (PubMed:27193680). Involved in the tail assembly
CC (PubMed:21129200). {ECO:0000269|PubMed:15315755,
CC ECO:0000269|PubMed:27193680, ECO:0000303|PubMed:21129200}.
CC -!- SUBUNIT: Heterotrimer with gp6; assembles as a (gp6)2-gp7
CC heterotrimeric molecule. The (gp6)2-gp7 heterotrimeric molecule further
CC interacts with gp25 and gp53. The gp25-(gp6)2-gp7 module is involved in
CC sheath contraction. Interacts with gp8. Binds to gp10 homotrimer;
CC disulfide-linked. Heteromultimer with gp10; a gp10 molecule is
CC disulfide-linked to gp7 and the other two remaining gp10 molecules form
CC a disulfide bond. Part of the baseplate macromolecular complex which
CC consists of gp5, gp5.4, gp27 (central spike complex); gp6, gp25, gp53
CC (inner baseplate); gp7, gp8 (intermediate baseplate); gp9, gp10, gp11,
CC gp12 (peripheral); gp48 and gp54 (proximal region of the tail tube).
CC {ECO:0000255|HAMAP-Rule:MF_04103, ECO:0000269|PubMed:27193680}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04103,
CC ECO:0000269|PubMed:15315755, ECO:0000269|PubMed:2254933,
CC ECO:0000269|PubMed:2403438, ECO:0000269|PubMed:27193680}. Note=Present
CC in 6 copies in the baseplate. {ECO:0000303|PubMed:21129200}.
CC -!- SIMILARITY: Belongs to the T4likevirus baseplate wedge protein gp7
CC family. {ECO:0000255|HAMAP-Rule:MF_04103}.
