Angiotensin I/II (5-8)

Angiotensin II (5-8), human is an endogenous C-terminal fragment of the peptide vasoconstrictor angiotensin II[1]. Angiotensin II binds the AT II type 1 (AT1) receptor, stimulating GPCRs in vascular smooth muscle cells and increasing intracellular Ca2+ levels. Angiotensin II also acts at the Na+/H+ exchanger in the proximal tubules of the kidney[2][3].

ChEBI: Angiotensin (5-8) is a dichlorobenzene.
