Bmi1 Gene Summary [Rat]
Predicted to enable several functions, including RING-like zinc finger domain binding activity; promoter-specific chromatin binding activity; and zinc ion binding activity. Involved in cellular response to dexamethasone stimulus; cellular response to interleukin-1; and regulation of kidney development. Predicted to be located in cytosol; heterochromatin; and nuclear body. Predicted to be part of PRC1 complex. Human ortholog(s) of this gene implicated in acute myeloid leukemia; colorectal carcinoma; hepatocellular carcinoma; and renal Wilms' tumor. Orthologous to several human genes including BMI1 (BMI1 proto-oncogene, polycomb ring finger). [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 rat Bmi1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
