    Summary
    Enables calcium ion binding activity and methylated-DNA-[protein]-cysteine S-methyltransferase activity. Involved in several processes, including DNA alkylation repair; cellular response to ionizing radiation; and mammary gland epithelial cell differentiation. Predicted to be located in membrane. Predicted to be active in nucleoplasm. Biomarker of colon adenocarcinoma and melanoma. 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, Nov 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.
