Protease-Activated Receptors (PAR) — frequently asked
What are protease-activated receptors?
They are G protein-coupled receptors, PAR-1 to PAR-4, activated when a protease cleaves their extracellular amino terminus. The newly exposed sequence acts as a tethered ligand that folds back and engages the receptor's own binding pocket.
What are tethered ligand peptides?
Short synthetic peptides copying the sequence revealed by cleavage can activate the receptor without protease treatment. They are widely used to study PAR signalling selectively, because proteases such as thrombin act on many substrates besides the receptor.
Are the catalogue peptides agonists?
The receptor fragment entries listed here correspond to defined receptor regions and are intended as immunogens, affinity ligands and blocking peptides for antibody work. They are not designed as receptor agonists and should not be assumed to activate signalling.
