| UniProt Protein Function: | 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. 3 isoforms of the human protein are produced by alternative splicing.Protein type: Nuclear export; Karyopherin; Receptor, misc.; Nuclear importChromosomal Location of Human Ortholog: 7q32.1Cellular Component: intracellular membrane-bound organelle; cytoplasm; nucleusMolecular Function: protein binding; receptor activityBiological Process: splicing factor protein import into nucleusDisease: Muscular Dystrophy, Limb-girdle, Type 1f |
| UniProt Protein Details: | |
| NCBI Summary: | The protein encoded by this gene is a nuclear import receptor for serine/arginine-rich (SR) proteins such as the splicing factors SFRS1 and SFRS2. The encoded protein has also been shown to be involved in HIV-1 infection, apparently through interaction with the HIV-1 capsid protein. Two transcript variants encoding different isoforms as well as a noncoding transcript have been found for this gene.[provided by RefSeq, Jul 2010] |
