Active Native Human Cathepsin D

• Cat.No.: CTSD-1648H
• Product Overview: Native Human Cathepsin D protein was purified from Human Liver

Specification

• Description: Cathepsin D is an estrogen-regulated protein associated with tissue breakdown. Levels of cathepsin D have been positively correlated with recurring breast cancers of both node-negative and node-positive types. Additionally cathepsin D has been associated with amyloid formation in Alzheimer's plaques. As cathepsin D activity is increased by cigarette smoke, the enzyme may contribute to lung tissue damage in smokers.
