Annotation transfered from Closely Related SWISS-PROT Entries

Annotation	Function Description	Confidence Level	Reference Protein
Importin subunit alpha-1	Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. Promotes docking of import substrates to the nuclear envelope. Seems to act as a cytosolic receptor for both simple and bipartite NLS motifs (By similarity). Cellular receptor for the nuclear import of the virD2 protein of Agrobacterium.	confident	Q96321
Importin subunit alpha-1b	Functions in nuclear protein import. Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. Promotes docking of import substrates to the nuclear envelope. In conjunction with importin beta-1, mediates the nuclear envelope docking, and the subsequent translocation into the nucleus of the constitutive morphogenetic 1 (COP1) protein containing bipartite NLS motif.	confident	Q9SLX0
Importin subunit alpha-7	Functions in nuclear protein import as an adapter protein for nuclear receptor KPNB1. Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. Docking of the importin/substrate complex to the nuclear pore complex (NPC) is mediated by KPNB1 through binding to nucleoporin FxFG repeats and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to importin-beta and the three components separate and importin-alpha and -beta are re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran from importin. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus.	probable	O60684
