Function
function
Assembles to form an icosahedral capsid with a T=1 symmetry, about 30 nm in diameter, and consisting of 60 capsid proteins F. Upon virus binding to host cell, one of the spikes dissociates from the capsid and the virus interacts with LPS through the exposed EF loops on the F proteins. After the genome had been ejected, the channel formed by the F proteins at the unique fivefold axis remains open.

Interaction
Subunit
Pentamerizes and interacts with H protein, G and B pentamers to form 12S pre-assembly complex. By binding with protein D, induces joining of twelve 12S complex to form the procapsid. The procapsid has an external scaffold made of 240 copies of protein D, 60 copies of the internally located B protein, and contains 60 copies of each of the viral structural proteins F and G. Upon genome packaging, interacts with protein J. The mature virion is composed of 60 copies each of the F, G, and J proteins, and 12 copies of the H protein.
