Endothelin 2, also known as ET-2, is a protein that in humans is encoded by the EDN2 gene.[5]

Function[edit]

Endothelin 2 is a member of the endothelin protein family of secretory vasoconstrictive peptides. The preproprotein is processed to a short mature form which functions as a ligand for the endothelin receptors that initiate intracellular signaling events. This gene product is involved in a wide range of biological processes, such as hypertension and ovulation.[5]

Endothelin 2 (ET-2) expression is mainly localized to the granulosa cells within the follicle, as observed in bovine, murine, and human ovarian tissue. Endothelin 2 has functions within the ovarian follicle related to ovulation. ET-2 causes strong contractions in smooth muscle cells of ovarian tissue, and ET-2 production is highest just before ovulation.[6][7][8][9]
