Interactioni

Subunit structurei

Interacts with the capsid vertex protein; this interaction allows tethering of the hexons surrounding the penton base to those situated in the central plate of the facet. Interacts with hexon protein; this interaction lashes hexons together, each copy of hexon-linking protein being bound to 4 hexon trimers.1 Publication

Miscellaneousi

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.
