SnapShot: Lysosomal Functions.

In addition to their well-defined recycling function, lysosomes act as metabolic signaling hubs that adjust cellular metabolism according to the availability of nutrients and growth factors by regulating metabolic kinases and transcription factors on their surface. Moreover, lysosomal hydrolases and ions released to cytosol or extracellular space have recently emerged as important regulators of various cellular processes from cell death to cell division.
