en·do·the·lin

(en'dō-thē'lin),
A 21-amino acid peptide originally derived from endothelial cells. It is an extremely potent vasoconstrictor. Three different gene products have been identified, endothelin 1, endothelin 2, and endothelin 3; they are found in brain, kidney, and endothelium (endothelin 1), intestine (endothelin 2), and intestine and adrenal gland (endothelin 3).

Measurement of bigET-1, which has slower clearance (14), has been proposed as an alternative approach for estimation of ET-1 release, but alterations in plasma bigET-1 may also not reflect changes in ET-1 synthesis because bigET-1 is cleaved at the tissue level not only into active ET-1, but also into the 31-amino acid endothelin peptide ET-[1.sub.(1-31)] by the action of chymase (15).
