Xpo1 Gene Summary [Mouse]
Enables nuclear export signal receptor activity. Involved in mRNA export from nucleus and protein export from nucleus. Acts upstream of or within several processes, including protein localization to nucleus; regulation of centrosome duplication; and regulation of protein export from nucleus. Located in nucleus. Is expressed in several structures, including alimentary system; brain; early embryo; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in colorectal cancer; gastric adenocarcinoma; hepatocellular carcinoma; and lung non-small cell carcinoma. Orthologous to human XPO1 (exportin 1).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Xpo1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
