Summary
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]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
