Function
function
Forms spikes that protrude from each vertex of the icosahedral capsid. Interacts with host receptor to provide virion initial attachment to target cell. Fiber proteins are shed during virus entry, when virus is still at the cell surface (By similarity).
Miscellaneous
All late proteins expressed from the major late promoter are produced by alternative splicing and alternative polyadenylation of the same gene giving rise to non-overlapping ORFs. A leader sequence is present in the N-terminus of all these mRNAs and is recognized by the viral shutoff protein to provide expression although conventional translation via ribosome scanning from the cap has been shut off in the host cell (By similarity).
