Capsid protein VP1

UniProtKB accession:  P24029

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Capsid protein self-assembles to form an icosahedral capsid with a T=1 symmetry, about 25 nm in diameter, and consisting of 60 copies of two size variants of the capsid proteins, VP1 (10% abundance) and VP2 (90% abundance), which differ by the presence of an N-terminal extension in the minor protein VP1. Capsid proteins are responsible for the attachment to host cell receptors. This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. VP1 binds DNA and may therefore play a role in viral DNA encapsidation.
