Baseplate hub protein gp44

UniProtKB accession:  P08558

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Forms the central cylindrical hub of the baseplate and plays an important role in baseplate and tail assembly (Probable). Core component of the initiator complex that triggers the tail tube polymerization during tail assembly (Probable). Forms a conduit that probably functions as an extension of the tail tube allowing viral DNA release during ejection. Might facilitate the interaction of the virus with the host cell surface through electrostatic interactions during virus entry into host cell.
