This gene encodes a nuclear RNA-binding protein of the heterogeneous nuclear ribonucleoprotein (hnRNP) family. This protein binds specifically to adenovirus E1B-55 kDa oncoprotein. It may play an important role in nucleocytoplasmic RNA transport, and its function is modulated by E1B-55 kDa in adenovirus-infected cells. Two transcript variants encoding different isoforms have been found for this gene. Additional variants have also been found, but their full-length natures have not been determined.
