FNIP1 is a multifunctional adaptor protein that integrates nutrient sensing, energy homeostasis, and organelle biogenesis by coupling AMPK signaling to mTORC1-TFEB-dependent transcriptional programs and by serving as a co-chaperone of Hsp90. FNIP1 forms a heterodimeric complex with folliculin (FLCN) that acts as a GAP for RagC/D GTPases, promoting mTORC1 lysosomal recruitment; AMPK phosphorylation of FNIP1 on multiple conserved serines (including S220) suppresses this GAP activity, enabling TFEB nuclear translocation and sequential waves of lysosomal and mitochondrial biogenesis (PMID:37079666, PMID:38324677). FNIP1 independently functions as a negative regulator of AMPK in B cells, heart, and skeletal muscle, where its loss causes developmental arrest of B and iNKT cells, cardiomyopathy, and a shift to oxidative slow-twitch fibers via the AMPK–PGC-1α axis (PMID:22608497, PMID:27303042, PMID:25548157). CK2-mediated phosphorylation of FNIP1 promotes its interaction with Hsp90 and incremental inhibition of Hsp90 ATPase activity, while PP5 dephosphorylation and O-GlcNAcylation target FNIP1 for ubiquitin-dependent degradation; additionally, FNIP1 binds SERCA to suppress Ca²⁺-dependent thermogenesis in adipocytes and binds phosphorylated STAT3 to limit its nuclear translocation (PMID:30699359, PMID:35412553, PMID:39262790).
