Anti-Dopamine beta Hydroxylase/DBH Antibody Picoband®

Dopamine beta-hydroxylase  (DBH), also known as  dopamine beta-monooxygenase, is an  enzyme  (EC1.14.17.1) that in humans is encoded by the DBH  gene. Dopamine beta-hydroxylase  catalyzes  the  chemical reaction. It is mapped to 9q34.2. The protein encoded by this gene is an oxidoreductase belonging to the copper type II, ascorbate-dependent monooxygenase family. The encoded protein, expressed in neuroscretory vesicles and chromaffin granules of the adrenal medulla, catalyzes the conversion of dopamine to norepinephrine, which functions as both a hormone and as the main neurotransmitter of the sympathetic nervous system. The enzyme encoded by this gene exists exists in both soluble and membrane-bound forms, depending on the absence or presence, respectively, of a signal peptide. Mutations in this gene cause dopamine beta-hydroxylate deficiency in human patients, characterized by deficits in autonomic and cardiovascular function, including hypotension and ptosis. Polymorphisms in this gene may play a role in a variety of psychiatric disorders.

Within the immune system initially reported to be selectively expressed in granulocytes (polymorphonuclear leukocytes [PMNs]) . Also detected in macrophages mycobacterial granulomas. Expressed in group2 innate lymphoid cells (ILC2s) during lung disease.
