Metabolite Identification
Common NameAngiotensin IV
DescriptionAngiotensin IV is one of the N-terminal angiotensin degradation products of angiotensin II. Angiotensin IV (AngIV) mediates important physiologic functions in the central nervous system, including blood flow regulation, processes underlying to learning and memory, and presents anticonvulsant activity. The presence of AngIV-specific binding sites has been identified in various mammalian tissues, including blood vessels, heart, kidney, and brain. Besides the presence of AngIV binding sites in the cardiovascular system, the major AngIV synthesizing enzymes aminopeptidase N (APN) and aminopeptidase B (APB) are also expressed in different cell types of this system. AngIV activates several protein kinases, including phosphatidylinositol 3 kinase, PI-dependent kinase-1, extracellular signal-related kinases (ERK), protein kinase B-α/Akt, and p70 ribosomal S6 kinase. AngIV could contribute to vascular damage, increasing the production of monocyte chemoattractant protein-1, the main chemokine involved in monocyte recruitment, and up-regulates the expression of the adhesion molecule intercellular adhesion molecule-1 that is involved in the attachment and transmigration of circulating cells into the damaged tissue.

General function:
Involved in proteolysis
Specific function:
Release of an N-terminal amino acid, cleaves before cysteine, leucine as well as other amino acids. Degrades peptide hormones such as oxytocin, vasopressin and angiotensin III, and plays a role in maintaining homeostasis during pregnancy. May be involved in the inactivation of neuronal peptides in the brain. Cleaves Met-enkephalin and dynorphin. Binds angiotensin IV and may be the angiotensin IV receptor in the brain
