| Post Translational Modifications | Phosphorylated by AMPK in response to energetic stress. Phosphorylation by AMPK in response to mitochondrial damage promotes inactivation of the non-canonical mTORC1 signaling, nuclear translocation of TFEB and TFE3, inducing transcription of lysosomal or autophagy genes. Sequential phosphorylation by CK2 promotes its gradual interaction with HSP90AA1/Hsp90. Priming phosphorylation at Ser-938 is followed by relay phosphorylation at Ser-939, Ser-941, Ser-946 and Ser-948, promoting its gradual interaction with HSP90AA1/Hsp90. This leads to incremental inhibition of HSP90AA1/Hsp90 ATPase activity and gradual activation of both kinase and non-kinase clients. Dephosphorylated by protein phosphatase 5 (PP5), promoting glycosylation by OGT. GlcNAcylation at Ser-938 by OGT following dephosphorylation by protein phosphatase 5 (PP5) promotes ubiquitination and degradation by the proteasome. Ubiquitinated through 'Lys-11' linkage of ubiquitin moieties at Lys-1119 following glycosylation by OGT, leading to its degradation by the proteasome. Ubiquitinated by the CRL2(FEM1B) complex in response to reductive stress: reductive stress causes reduction of the conserved Cys degron in FNIP1, followed by zinc-binding, zinc acting as a molecular glue for recognition by the CRL2(FEM1B) complex. Ubiquitination leads to FNIP1 degradation, and activation of mitochondria to recalibrate reactive oxygen species (ROS). Oxidation of the Cys degron in normal conditions promotes its stabilization by preventing recognition and ubiquitination by the CRL2(FEM1B) complex. |
| Function | Binding partner of the GTPase-activating protein FLCN: involved in the cellular response to amino acid availability by regulating the non-canonical mTORC1 signaling cascade controlling the MiT/TFE factors TFEB and TFE3. Required to promote FLCN recruitment to lysosomes and interaction with Rag GTPases, leading to activation of the non-canonical mTORC1 signaling. In low-amino acid conditions, component of the lysosomal folliculin complex (LFC) on the membrane of lysosomes, which inhibits the GTPase-activating activity of FLCN, thereby inactivating mTORC1 and promoting nuclear translocation of TFEB and TFE3. Upon amino acid restimulation, disassembly of the LFC complex liberates the GTPase-activating activity of FLCN, leading to activation of mTORC1 and subsequent inactivation of TFEB and TFE3. Together with FLCN, regulates autophagy: following phosphorylation by ULK1, interacts with GABARAP and promotes autophagy. In addition to its role in mTORC1 signaling, also acts as a co-chaperone of HSP90AA1/Hsp90: following gradual phosphorylation by CK2, inhibits the ATPase activity of HSP90AA1/Hsp90, leading to activate both kinase and non-kinase client proteins of HSP90AA1/Hsp90. Acts as a scaffold to load client protein FLCN onto HSP90AA1/Hsp90. Competes with the activating co-chaperone AHSA1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins. Also acts as a core component of the reductive stress response by inhibiting activation of mitochondria in normal conditions: in response to reductive stress, the conserved Cys degron is reduced, leading to recognition and polyubiquitylation by the CRL2(FEM1B) complex, followed by proteasomal. Required for B-cell development. |
