Endothelin (ET) — frequently asked

What is the endothelin family?
It is a group of three 21-residue disulfide-bonded peptides, endothelin-1, -2 and -3, produced from preproendothelin precursors. They are studied as endogenous ligands of the ETA and ETB G protein-coupled receptors in vascular and non-vascular tissues.
Why is endothelin studied in the laboratory?
Researchers use endothelin peptides to probe vasoconstriction, receptor subtype selectivity, converting-enzyme processing and downstream signalling. The peptides also serve as calibration standards and immunogens in assays that measure endothelin content in cell culture medium and tissue extracts.
Which species variants are available?
Mature endothelin-1 is identical across many mammals, so a single sequence is often listed for human, rat, mouse, porcine, bovine, canine, rabbit and monkey work. Precursor-derived fragments and antibodies are usually species-specific and labelled accordingly.
