Description
OverviewCathepsin K is a member of the papain superfamily of cysteine proteinases and plays an important role in osteoclast-mediated bone resorption and collagen degradation. It is primarily expressed by osteoclasts and recent studies also suggest its expression in fibroblasts. Irregularities in cathepsin K activity, either too high or too low, contribute to osteopenic disorders such as osteoporosis and pycnodysostosis. This recombinant enzyme contains a C-terminal His•Tag® sequence.
Note: 1 mU = 1 milliunit.
