    Summary
    Enables methyltransferase activity. Acts upstream of or within DNA alkylation repair and regulation of cysteine-type endopeptidase activity involved in apoptotic process. Predicted to be active in nucleoplasm. Is expressed in embryo and forelimb bud. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); endocrine gland cancer (multiple); granulosa cell tumor; high grade glioma (multiple); and retinoblastoma. Orthologous to human MGMT (O-6-methylguanine-DNA methyltransferase). [provided by Alliance of Genome Resources, Dec 2024]

    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.
