Ctsb lysosome
Cathepsin B belongs to a family of lysosomal cysteine proteases known as the cysteine cathepsins and plays an important role in intracellular proteolysis. In humans, cathepsin B is encoded by the CTSB gene. Cathepsin B is upregulated in certain cancers, in pre-malignant lesions, and in various other … See more Gene The CTSB gene is located at chromosome 8p22, consisting of 13 exons. The promoter of CTSB gene contains a GC-rich region including many SP1 sites, which is similar to See more Cathepsin B may enhance the activity of other proteases, including matrix metalloproteinase, urokinase (serine protease rokinase … See more Cathepsin B has been shown to interact with: • CTSD • CSTA, See more • The MEROPS online database for peptidases and their inhibitors: C01.060 • Cathepsin+B at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more Cathepsin B has been proposed as a potentially effective biomarker for a variety of cancers.

We proposed that CTSB cleaves MCOLN1 in the lysosome, which would result in a reduction of calcium efflux from the lysosomal lumen to the cytoplasm. Indeed, we found that cleavage of MCOLN1 is abolished in the lysosomes of CTSB-deficient BMDMs. Furthermore, we …
