proendothelin2

Proendothelin2 is the precursor protein for endothelin-2 (ET-2). Endothelin-2 is a potent vasoconstrictor peptide, meaning it narrows blood vessels, which can increase blood pressure. Proendothelin2 is synthesized as a larger inactive molecule within cells. This precursor undergoes enzymatic cleavage to produce the active endothelin-2 peptide. The expression and processing of proendothelin2 are tightly regulated, as endothelin-2 plays roles in various physiological processes, including cardiovascular regulation, renal function, and cell growth. Aberrant production or signaling of endothelin-2 has been implicated in conditions such as hypertension, pulmonary hypertension, and certain types of cancer. Research into proendothelin2 and its processing pathways is ongoing to better understand its physiological and pathological functions and to develop potential therapeutic targets. The conversion of proendothelin2 to endothelin-2 involves specific proteases that cleave the precursor at distinct sites. The resulting endothelin-2 peptide then binds to specific receptors on target cells to exert its effects.
