In addition to transporting tumor suppressor proteins out of the nucleus, XPO1 can interact with specific RNA‐binding proteins to co‐transport oncogene mRNA out of the nucleus, promote translation, and exert tumor‐promoting activity.[19] PTBP1 is highly expressed in several tumors and associated with tumorigenesis.[55] PTBP1 is an RNA‐binding protein that regulates multiple aspects of the messenger RNA life cycle, including splicing, 3′‐end processing, localization, stability, and translation. The gene discussed is PTBP1; the disease is neoplasm.
