Protein Name:
Importin subunit alpha-1
|
UniprotKB/SwissProt ID: Q96321 (Q96321)
Gene Name:
IMPA1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: 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, PubMed:37676567). Involved in the maintenance of cell wall integrity under salt stress via interaction with SWO1 (PubMed:37676567). Acts as a cellular receptor for the nuclear import of the virD2 protein of Agrobacterium, but is not essential for Agrobacterium-mediated root transformation (PubMed:18836040)
