Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Encapsidates the viral genome into characteristic twinned ('geminate') particles. Binds the genomic viral ssDNA and shuttles it into and out of the cell nucleus. Plays a role in protection of the genome from degradation, virus acquisition and transmission by insect vectors, infectivity, and systemic movement. The CP of monopartite geminiviruses is absolutely essential for virus movement (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
