UniprotKB/SwissProt ID: F4IRR2 (F4IRR2)
Gene Name:
SAD2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Functions probably in nuclear protein import, either by acting as autonomous nuclear transport receptor or as an adapter-like protein in association with other importin subunits (Probable). Involved in the regulation of the abscisic acid (ABA)-mediated pathway in response to cold or salt stress (PubMed:16889648). Involved in UV-B responses by regulating accumulation of UV-absorbing pigments through mediation of MYB4 nuclear transport (PubMed:17993626). Involved in trichome initiation by controlling GL1, GL2, GL3 and TTG1 transcription and may affect an upstream regulator of GL3 and disrupt complex function (PubMed:18713401, PubMed:19234066). Acts as a negative regulator miRNA activity by regulating miRNA loading into AGO1 complexes (PubMed:21984696)
