MITF has been implicated in the regulation of expression of many components of the v-ATPase, including the cytosolic component ATP6V1B2 (Zhang et al, 2015). The v-ATPase is responsible for acidification of organelles such as the lysosome and the endosome. The lysosome is also a site of regulation of TORC1 (target of rapamycin complex 1) that promotes global protein synthesis. MITF-family members and TORC1 play varied but interconnected roles in the sensing and response to nutrient levels, with MITF either positively or negatively regulating TORC activity depending on context (reviewed in Martina et al, 2014), and TORC1 and RAG GTPases have been shown to regulate the localization of some MITF family members (Martina and Puertollano, 2019). MITF has also been implicated as a regulator in a subset of genes associated with autophagy and lysosome biogenesis (Ploper et al, 2015; Moller et al, 2019; reviewed in Ploper and Robertis, 2015; Goding and Arnheiter, 2019).
