Summary: Enables catechol O-methyltransferase activity. Acts upstream of or within several processes, including catecholamine metabolic process; learning or memory; and signal release. Located in mitochondrion. Is active in cytosol and vesicle. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system; and sensory organ. Used to study cognitive disorder and pre-eclampsia. 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]
Expression: Broad expression in liver adult (RPKM 254.4), subcutaneous fat pad adult (RPKM 175.4) and 25 other tissues See more

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.
