Regulation of MITF-M-dependent genes involved in lysosome biogenesis and autophagy

Regulation of MITF-M-dependent genes involved in lysosome biogenesis and autophagy MITF regulates biogenesis of organelles such as the lysosome and endosomes through its regulation of components of the V-ATPase that is required for organelle acidification and function (Zhang et al, 2015; Ploper et al, 2015a; reviewed in Ploper et al, 2015b). MITF-dependent targets also contribute to autophagy when cells are stressed for nutrients (Möller et al, 2019). MITF additionally controls expression of the lysosome-resident acid ceramidase ASAH1 that has roles in sphingolipid metabolism and cellular proliferation in melanoma (Leclerc et al, 2019; Realini et al, 2016).
