Family

Adenovirus penton base protein (IPR002605)

Short name: Adeno_Penton_B

Family relationships

None.

Description

This family consists of various adenovirus penton base proteins (also known as Protein III) [PMID: 20798312], from both the mastadenoviridae having mammalian hosts and the aviadenoviridae having avian hosts. The penton base is a major structural protein forming part of the penton which consists of a base and a fibre, the pentons hold a morphologically prominent position at the vertex capsomer in the adenovirus particle [PMID: 1316685]. In mammalian adenovirus there is only one tail on each base where as in avian adenovirus there are two [PMID: 1316685].

The penton base proteins are also Involved in virus secondary attachment to host cell after initial attachment by the fibre protein [PMID: 20615244].
