Human PAI-1 (substrate form – P12 Glutamate mutant)
From the laboratory of Professor Paul Declerck – Leuven BELGIUM. A single substitution at position P12 in the reactive center loop produces a PAI-1 that becomes a substrate for proteinases rather than an inhibitor. Reactive center loop insertion follows protease cleavage and the PAI-1 loses vitronectin binding properties. This molecule is useful for mechanistic studies.
