IPO3 Seems to function in nuclear protein import as nuclear transport receptor. In vitro, mediates the nuclear import of splicing factor SR proteins RBM4, SFRS1 and SFRS2, by recognizing phosphorylated RS domains. Expressed in skeletal muscle. 4 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
