NCBI Protein Information
ARM repeat superfamily protein
NCBI Summary
Encodes a karyopherin, specifically the Arabidopsis ortholog of LOS1/XPOT, a protein that mediates nuclear export of tRNAs in yeast and mammals. PSD is capable of rescuing the tRNA export defect of los1 in S. cerevisiae. psd mutants display disrupted initiation of the shoot apical meristem and delay leaf initiation after germination; they also display delayed transition from vegetative to reproductive development.

UniProt Comments
Probable tRNA nucleus export receptor which regulates tRNA processing and facilitates tRNA translocation across the nuclear pore complex. Is required for proper activity of the shoot apical meristem (SAM) and correct leaf initiation at different developmental stages, and may play a role in floral patterning.
