Cbx4 Gene Summary [Mouse]
Enables several functions, including SUMO binding activity; SUMO transferase activity; and phosphoprotein binding activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II and protein sumoylation. Located in nuclear body. Is expressed in several structures, including adrenal gland; brain; gut; lung; and thymus. Human ortholog(s) of this gene implicated in hepatocellular carcinoma. Orthologous to human CBX4 (chromobox 4). [provided by Alliance of Genome Resources, Jul 2025]

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 Cbx4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
