WebOur study demonstrates that under homeostatic conditions CTSB cleaves the calcium channel MCOLN1/TRPML1 in the lysosomes, maintaining suppression of the transcription factor TFEB and reducing expression of lysosomal and autophagy-related proteins. This response controls the number of lysosomes and autophagosomes in the cell. Webof CTSB impairs cleavage of the calcium channel MCOLN1/ TRPML1. 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 … greenwich office space for lease https://nhukltd.com
