Activity summary

COMT also known as catechol-O-methyltransferase is an enzyme responsible for the methylation of catechol compounds including neurotransmitters like dopamine epinephrine and norepinephrine. This reaction requires S-adenosylmethionine as a methyl donor. COMT primarily has two forms: a soluble form and a membrane-bound form with masses around 24 kDa and 30 kDa respectively. This protein shows significant expression in the liver brain and kidneys. COMT expression is also noted in cell lines such as HEK293T where it plays an important role in catecholamine metabolism.

Biological function summary

Catechol-O-methyltransferase serves as a regulator of neurotransmitter levels in the central nervous system and peripheral tissues. It does not appear to form part of a larger protein complex functioning mainly as a singular entity for metabolizing catechols. Through its action COMT impacts processes such as mood regulation cognition and stress response. Its role in degrading dopamine is especially significant in regions like the prefrontal cortex where dopamine plays an important role in executive functions.

Pathways

COMT participates in the catecholamine degradation pathway and impacts dopaminergic signaling. It works alongside enzymes such as monoamine oxidase (MAO) to regulate levels of neurotransmitters. COMT's activity influences the synaptic presence of dopamine and its interaction in signaling pathways. Moreover it indirectly affects the balance within the dopaminergic system which is important for normal neurological function and behavior.

Associated diseases and disorders

COMT has links to psychiatric and neurological conditions such as schizophrenia and Parkinson’s disease. Variations in COMT function can affect dopamine metabolism which may contribute to the etiology of these disorders. Additionally proteins like MAO and dopamine transporter (DAT) also connect to COMT through their shared involvement in neurotransmitter regulation. Alterations in COMT activity can influence disease severity and patient response to treatment underlining its importance in understanding these disorders.
