Mdm2 Gene Summary [Rat]
Enables p53 binding activity; signaling receptor binding activity; and ubiquitin protein ligase activity. Involved in several processes, including cellular response to UV-C; cellular response to estrogen stimulus; and regulation of macromolecule metabolic process. Is active in glutamatergic synapse and postsynaptic density. Used to study ichthyosis; post-traumatic stress disorder; and transient cerebral ischemia. Biomarker of breast cancer; intermittent claudication; liver disease; and priapism. Human ortholog(s) of this gene implicated in chronic myeloid leukemia; glioblastoma; hepatocellular carcinoma; pancreatic ductal carcinoma; and sarcoma. Orthologous to human MDM2 (MDM2 proto-oncogene). [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 Mdm2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
