Protein
Nuclear shuttle protein
Organism
Bean golden yellow mosaic virus (isolate Puerto Rico-Japan)
Function
Binds to the genomic viral ssDNA, shuttles it into and out of the cell nucleus. Begomoviruses use 2 proteins to transport their DNA from cell to cell. The nuclear shuttle protein (NSP) shuttles it between nucleus and cytoplasm and the movement protein (MP) probably transports the DNA-NSP complex to the cell periphery and facilitates movement across the cell wall (By similarity).
Similarity
Belongs to the begomovirus nuclear shuttle protein family.
