NCBI Protein Information
nuclear shuttle interacting
NCBI Summary
Encodes a nuclear acetyltransferase (NSI)that interacts with the geminivirus movement protein NSP. This interaction is required for viral infection and systemic spread. Acetylates the viral coat protein (CP) in vitro, but not NSP. NSP inhibits NSI activity in vitro. NSI is highly transcribed in phloem and in xylem parenchyma cells, and in the apical meristem and guard cells, within young tissues in Arabidopsis, and its expression is turned off as tissues mature.

UniProt Comments
Acetyltransferase that acetylates in vitro histones H2A and H3. Does not act as a transcriptional activator but might be involved in the sink-source transition. In case of begomoviruses infection, acetylates the capsid protein (CP), but not the nuclear shuttle protein (NSP). Required for begomovirus infection and systemic spread.
