Anti-Cytochrome b561

Biological Activity

CYB561 (cytochrome b561) is responsible for the regeneration of ascorbate, by functioning as monodehydroascorbate reductase. It is also involved in transmembrane transport, where it acts as Fe3+-reductase, and reduces iron. It also plays a role in defense against stress, modifications of cell wall, neurological processes such as memory formation, metabolism of iron and suppression of tumor. It is involved in catecholamine synthesis, where it acts as storage vesicle membrane electron shuttle. It is the source of reduced equivalents to two monooxygenases- peptidylglycine α-amidating monooxygenase in neurosecretory vesicles and dopamine β-hydroxylase in chromaffin granules. Polymorphism in this gene is associated with inherited changes in both basal and stress-related heart rate.
