CC -!- FUNCTION: Probable tRNA nucleus export receptor which regulates tRNA
CC processing and facilitates tRNA translocation across the nuclear pore
CC complex. Is required for proper activity of the shoot apical meristem
CC (SAM) and correct leaf initiation at different developmental stages,
CC and may play a role in floral patterning. {ECO:0000269|PubMed:12913148,
CC ECO:0000269|PubMed:12913168, ECO:0000269|PubMed:15738428}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Note=Shuttles between the nucleus and the cytoplasm. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in young leaves, growing leaf blades,
CC young floral organs and root tips. {ECO:0000269|PubMed:12913148}.
CC -!- DISRUPTION PHENOTYPE: Delayed leaf formation during vegetative
CC development, abnormal SAM layered structure, altered inflorescences,
CC disrupted phyllotaxy, reduced number of seeds and reduced number of
CC lateral roots. {ECO:0000269|PubMed:12913148,
CC ECO:0000269|PubMed:12913168}.
CC -!- SIMILARITY: Belongs to the exportin family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG51863.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
