Predicted to enable nuclear localization sequence binding activity. Predicted to be a structural constituent of nuclear pore. Predicted to be involved in RNA export from nucleus; nuclear pore organization; and protein import into nucleus. Predicted to act upstream of or within mRNA transport and protein transport. Predicted to be located in nuclear membrane and nucleoplasm. Predicted to be part of nuclear pore. Is expressed in several structures, including genitourinary system; gut; integumental system; liver and biliary system; and nervous system. Orthologous to several human genes including POM121 (POM121 transmembrane nucleoporin). [provided by Alliance of Genome Resources, Apr 2022]
