背景资料

Catechol-O-methyltransferase (COMT) plays an important role in normal brain function and has been implicated in human disorders, such as Parkinson's disease. Using S-adenosyl-L-methionine (SAM) as a methyl donor, COMT methylates catechol substrates, which include neurotransmitters, such as dopamine, norepinephrine, epinephrine, and catecholestrogens; ascorbic acid; and carcinogenic flavonoids.{26885} There are two classes of COMT, the soluble cytosolic form (S-COMT), and the rough endoplasmic reticulum membrane bound form (MB-COMT).{26887} Both forms are coded by a single gene using two separate promoters.{26887} Cayman’s COMT is the soluble S-COMT isoform and is composed of 221 amino acids, whereas MB-COMT has an additional 50 amino acid residues, including 21 hydrophobic amino acid residues that compose the membrane anchor region.{26884} While S-COMT is predominate in most tissues, MB-COMT is found in higher concentrations in the brain.{26888} A common variant in exon 4 of the COMT gene leads to a substitution of valine by methionine,Val158Met, which affects the stability of COMT and may diminish activity by 50% in the human brain. Since COMT is one of the primary regulators of prefrontal cortex dopamine levels, it plays an important role in cognition.{26886}
