| Description : |
Endothelinconvertingenzymes (ECEs) hydrolyze a specific peptide bond of big endothelins to produceactive endothelins, some of the most potent vasoconstrictors known. Ece1 is amember of the M13 zinc metallopeptidase family. Other members of the M13 familyinclude thermolysin, neprilysin, Kell, and ECE2. M13 metallopeptidases can bedistinguished from other metallopeptidases by their sensitivity to inhibitionby phosphoramidon. Ece1 displays pronounced Ph dependence in its substrate specificity.The degradation of Substance P by Ece1 in endosomes regulates βarrestindependentERK2 signaling to prevent cell death in some neuronal cells. Four isoforms ofEce1 are present in humans and mice, all of which encode a Type II integral membraneprotein. The four isoforms share a common extracellular catalytic domain, differingin their Nterminal cytoplasmic tail regions. The recombinant mouse Ece1 transmembraneand cytoplasmic tail domains were replaced with a signal sequence, resulting inthe secretion of the soluble catalytic ectodomain. |
