Summary: Enables catechol O-methyltransferase activity. Involved in several processes, including learning or memory; negative regulation of dopamine metabolic process; and positive regulation of homocysteine metabolic process. Located in several cellular components, including cell body; dendritic spine; and postsynaptic membrane. Is active in glutamatergic synapse and postsynapse. Used to study Parkinsonism and hypertension. Biomarker of hypertension. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease of skin and connective tissue (multiple); cognitive disorder (multiple); drug dependence (multiple); reproductive organ cancer (multiple); and withdrawal disorder (multiple). Orthologous to human COMT (catechol-O-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.
