General annotation (Comments)

Function

Capsid protein self-assembles to form an icosahedral capsid with a T=1 symmetry, about 22 nm in diameter, and consisting of 60 copies of two size variants of the capsid proteins, VP1 and VP2, which differ by the presence of an N-terminal extension in the minor protein VP1. The capsid encapsulates the genomic ssDNA. Capsid proteins are responsible for the attachment to host cell receptors. This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. Binding to the host receptors also induces capsid rearrangements leading to surface exposure of VP1 N-terminus, specifically its phospholipase A2-like region and putative nuclear localization signal(s). VP1 N-terminus might serve as a lipolytic enzyme to breach the endosomal membrane during entry into host cell and might contribute to virus transport to the nucleus By similarity.

Subcellular location

Virion By similarity. Host nucleus Potential.

Domain

The N-terminus of VP1 is sequestered within the mature capsid. It contains a phospholipase A2-like region and putative nuclear localization signals.

Miscellaneous

VP3 might be a post-translational cleavage product of VP2 in several autonomous parvoviruses.

Sequence similarities

Belongs to the parvoviridae capsid protein family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform VP1 (identifier: P18546-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Note: Minor splicing isoform.
Isoform VP2 (identifier: P18546-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-150: Missing.
Note: Major splicing isoform produced by deletion of the initiating AUG for VP1 and downstream translation of VP2.
