Biochem/physiol Actions
Cathepsin D, a ubiquitous aspartic protease belonging to the A1 peptidase family, is found intracellularly in lysosomes. The enzyme has been associated with various biological processes such as: apoptotic events (e.g., the release of cytochrome c from mitochondria and the loss of the transmembrane potential (ΔΨ), aging, Alzheimer′s disease, and breast cancer.
Features and Benefits
- Contains all the reagents required for the measurement of the cathepsin D activity in cell and tissue lysates.
- The bottom limit of detection is 750 pg of protein (or 13 femtomoles of enzyme).
- A single step reaction with direct, real time observation of the degradation product released by the enzyme.
- The kit has been tested on extracts from CHO, HeLa, HEK 293, A431, HepG2, U937, and Jurkat cells on S. cerevisiae and on rat brain, kidney and liver tissues.
Analysis Note
The assay is based on the hydrolysis, by the enzyme, of an internally quenched fluorimetric substrate.

Liver sinusoidal endothelial cells (LSECs) are largely responsible for the removal of circulating lysosomal enzymes (LE) via mannose receptor (MR)-mediated endocytosis. We hypothesized that LSECs rely on this uptake to maintain their extraordinarily high degradation capacity for other endocytosed material.

The major function of the Haptoglobin (Hp) protein is to control trafficking of extracorpuscular hemoglobin (Hb) thru the macrophage CD163 receptor with degradation of the Hb in the lysosome. There is a common copy number polymorphism in the Hp gene

In phagocytic cells, including the retinal pigment epithelium (RPE), acidic compartments of the endolysosomal system are regulators of both phagocytosis and autophagy, thereby helping to maintain cellular homeostasis. The acidification of the endolysosomal system is modulated by a proton pump
