Cbx8 Gene Summary [Rat]
Predicted to enable several functions, including methylated histone binding activity; single-stranded RNA binding activity; and ubiquitin-protein transferase activator activity. Involved in cellular response to hydrogen peroxide; positive regulation of cell population proliferation; and positive regulation of metabolic process. Predicted to be located in heterochromatin and nucleoplasm. Predicted to be part of PRC1 complex. Predicted to be active in chromatin. Orthologous to human CBX8 (chromobox 8).

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 rat Cbx8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
