Abstract

The view of the lysosome as the terminal end of cellular catabolic pathways has been challenged by recent studies showing a central role of this organelle in the control of cell function. Here we show that a lysosomal Ca2+ signalling mechanism controls the activities of the phosphatase calcineurin and of its substrate TFEB, a master transcriptional regulator of lysosomal biogenesis and autophagy. Lysosomal Ca2+ release through mucolipin 1 (MCOLN1) activates calcineurin, which binds and dephosphorylates TFEB, thus promoting its nuclear translocation. Genetic and pharmacological inhibition of calcineurin suppressed TFEB activity during starvation and physical exercise, while calcineurin overexpression and constitutive activation had the opposite effect. Induction of autophagy and lysosomal biogenesis through TFEB required MCOLN1-mediated calcineurin activation. These data link lysosomal calcium signalling to both calcineurin regulation and autophagy induction and identify the lysosome as a hub for the signalling pathways that regulate cellular homeostasis.

**Figure 8**
Model of Ca²⁺ mediated regulation of TFEB. Under normal feeding conditions TFEB is phosphorylated on the lysosomal surface and is sequestered in the cytoplasm by the 14-3-3 proteins. During starvation and physical exercise Ca²⁺ is released from the lysosome via MCOLN1, thus establishing a Ca²⁺ microdomain. This leads to calcineurin activation and TFEB de-phosphorylation. De-phosphorylated TFEB is no longer able to bind 14-3-3 proteins and can freely translocate to the nucleus where it transcriptionally activates the lysosomal/autophagic pathway.
