General description

The gene Catechol-O-methyltransferase (COMT) is mapped to human chromosome 22q11.2. COMT is also referred to as HEL-S-98n. It is widely expressed in various tissues, including brain, liver, kidney, endometrium and breast.

Specificity

The antibody recognizes MB-COMT and S-COMT.

Application

Anti-COMT (N-terminal) antibody produced in rabbit has been used in immunoblotting.

Biochem/physiol Actions

Catechol-O-methyltransferase (COMT) is a Mg2+-dependent enzyme. COMT catalyzes transfer of methyl groups from S-adenosyl methionine to catecholamines. It is responsible for degradation of catecholamines and thereby results in psychiatric disorders and symptoms. Met/Met genotype individuals can acquire skill in executive function tasks (as multi-unmanned vehicles supervisory control, to a higher level and/or faster than other genotype groups). On the other hand, COMT polymorphism is linked to major depressive disorder and bipolar disorder. The genetic variants of COMT alter neurobehavioral functions that are affected by mercury in adults and might modify the adverse neurobehavioral effects of mercury exposure in children. COMT polymorphism is associated with high risk of premature ovarian insufficiency. COMT single nucleotide polymorphism preoperative humans psychological status and postoperative opioid analgesia efficacy. COMT acts as a tumor supressor gene for colorectal cancer cell lines. Overexpression of COMT supresses pancreatic cancer.
