Enzyme Function FUNCTION: Structural component of the virion that acts as a cement protein on the capsid exterior which mediates the interactions between the hexons, including the peripentonal hexons, and reaches all the way to the penton vertices. Two hexon linking proteins IIIa, one from each facet, stabilize the unique edge interface between a pair of facets. As the virus enters the host cell, hexon linking proteins IIIa are shed concomitant with virion acidification in the endosome. During virus assembly, seems to play a role in the serotype specificity of the packaging of viral DNA via its interaction with packaging protein 3. {ECO:0000255|HAMAP-Rule:MF_04047}.
