kinin
PWM-PK-3 is a peptide sequence corresponding to a peptide fragment in the aminoterminal area of bradykinin, a peptide hormone that is involved in inflammation and the regulation of blood pressure in the body. It is composed of the three amino acids Proline, Valine, and Lysine. Bradykinin is known to bind to G protein-coupled receptors, specifically B2 receptor, which causes an increase in intracellular calcium levels and leads to vasodilation. Thus, PWM-PK-3 is believed to be involved in the activation of the B2 receptor and could play a vital role in the regulation of inflammation and blood pressure in the body.
