NCBI Protein Information
importin alpha isoform 1
NCBI Summary
Encodes importin alpha involved in nuclear import. Protein interacts with Agrobacterium proteins VirD2 and VirE2. Is not individually essential for Agrobacterium-mediated root transformation, but when overexpressed can rescue the impa-4 decreased transformation susceptibility phenotype.

UniProt Comments
Binds to conventional NLS motifs with high affinity in the absence of an importin beta subunit. Mediates nuclear protein import across the nuclear envelope in vitro in the absence of exogenously added importin beta subunit (PubMed:10428841). Acts as cellular receptor for the nuclear import of the virD2 protein of Agrobacterium, but is not essential for Agrobacterium-mediated root transformation (PubMed:18836040).
