FLCN (Folliculin) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a drug target, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Renal cell carcinoma, Colorectal cancer, Gastric & gastro-oesophageal junction cancer and 3 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Multi-functional protein, involved in both the cellular response to amino acid availability and in the regulation of glycolysis. GTPase-activating protein that plays a key role in the cellular response to amino acid availability through regulation of the non-canonical mTORC1 signalling cascade controlling the MiT/TFE factors TFEB and TFE3. Activates mTORC1 by acting as a GTPase-activating protein: specifically stimulates GTP hydrolysis by RagC/RRAGC or RagD/RRAGD, promoting the conversion to the GDP-bound state of RagC/RRAGC or RagD/RRAGD, and thereby activating the kinase activity of mTORC1. The GTPase-activating activity is inhibited during starvation and activated in presence of nutrients. Acts as a key component for non-canonical mTORC1-dependent control of the MiT/TFE factors TFEB and TFE3, while it is not involved in mTORC1-dependent phosphorylation of canonical RPS6KB1/S6K1 and EIF4EBP1/4E-BP1. In low-amino acid conditions, the lysosomal folliculin complex (LFC) is formed on the membrane of lysosomes, which inhibits the GTPase-activating activity of FLCN, inactivates mTORC1 and maximises nuclear translocation of TFEB and TFE3.
