Also known as KIAA0243LAMhamartin
Summary
TSC1 (TSC complex subunit 1, HGNC:12362) is a protein-coding gene on chromosome 9q34.13, encoding Hamartin (Q92574). Non-catalytic component of the TSC-TBC complex, a multiprotein complex that acts as a negative regulator of the canonical mTORC1 complex, an evolutionarily conserved central nutrient sensor that stimulates anabolic reactions and macromolecule biosynthesis to promote cellular bio…. In precision oncology, TSC1 Loss-of-function confers sensitivity to Everolimus in Tuberous Sclerosis (CIViC Level A); 4 further curated variant–drug associations are listed below. It is haploinsufficient (ClinGen: sufficient evidence).
This gene is a tumor suppressor gene that encodes the growth inhibitory protein hamartin. The encoded protein interacts with and stabilizes the GTPase activating protein tuberin. This hamartin-tuberin complex negatively regulates mammalian target of rapamycin complex 1 (mTORC1) signaling which is a major regulator of anabolic cell growth. This protein also functions as a co-chaperone for Hsp90 that inhibits its ATPase activity. This protein functions as a facilitator of Hsp90-mediated folding of kinase and non-kinase clients, including TSC2 and thereby preventing their ubiquitination and proteasomal degradation. Mutations in this gene have been associated with tuberous sclerosis and lymphangioleiomyomatosis.

Function. Non-catalytic component of the TSC-TBC complex, a multiprotein complex that acts as a negative regulator of the canonical mTORC1 complex, an evolutionarily conserved central nutrient sensor that stimulates anabolic reactions and macromolecule biosynthesis to promote cellular biomass generation and growth. The TSC-TBC complex acts as a GTPase-activating protein (GAP) for the small GTPase RHEB, a direct activator of the protein kinase activity of mTORC1. In absence of nutrients, the TSC-TBC complex inhibits mTORC1, thereby preventing phosphorylation of ribosomal protein S6 kinase (RPS6KB1 and RPS6KB2) and EIF4EBP1 (4E-BP1) by the mTORC1 signaling. The TSC-TBC complex is inactivated in response to nutrients, relieving inhibition of mTORC1. Within the TSC-TBC complex, TSC1 stabilizes TSC2 and prevents TSC2 self-aggregation. Acts as a tumor suppressor. Involved in microtubule-mediated protein transport via its ability to regulate mTORC1 signaling. Also acts as a co-chaperone for HSP90AA1 facilitating HSP90AA1 chaperoning of protein clients such as kinases, TSC2 and glucocorticoid receptor NR3C1. Increases ATP binding to HSP90AA1 and inhibits HSP90AA1 ATPase activity. Competes with the activating co-chaperone AHSA1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins. Recruits TSC2 to HSP90AA1 and stabilizes TSC2 by preventing the interaction between TSC2 and ubiquitin ligase HERC1.
Subunit / interactions. Component of the TSC-TBC complex (also named Rhebulator complex), composed of 2 molecules of TSC1, 2 molecules of TSC2 and 1 molecule of TBC1D7. Probably forms a complex composed of chaperones HSP90 and HSP70, co-chaperones STIP1/HOP, CDC37, PPP5C, PTGES3/p23, TSC1 and client protein TSC2. Forms a complex composed of chaperones HSP90 and HSP70, co-chaperones CDC37, PPP5C, TSC1 and client protein TSC2, CDK4, AKT, RAF1 and NR3C1; this complex does not contain co-chaperones STIP1/HOP and PTGES3/p23. Forms a complex containing HSP90AA1, TSC1 and TSC2; TSC1 is required to recruit TCS2 to the complex. Interacts (via C-terminus) with the closed form of HSP90AA1 (via the middle domain and TPR repeat-binding motif). Interacts with DOCK7. Interacts with FBXW5. Interacts with WDR45B. Interacts with RPAP3 and URI1.
Subcellular location. Lysosome membrane. Cytoplasm. Cytosol.
Tissue specificity. Highly expressed in skeletal muscle, followed by heart, brain, placenta, pancreas, lung, liver and kidney. Also expressed in embryonic kidney cells.
Post-translational modifications. Phosphorylation at Ser-505 does not affect interaction with TSC2. ‘Lys-63’-linked ubiquitinated at Lys-30 by PELI1; the ubiquitination promotes TSC1/TSC2 complex stability.
Disease relevance. Tuberous sclerosis 1 (TSC1) [MIM:191100] An autosomal dominant multi-system disorder that affects especially the brain, kidneys, heart, and skin. It is characterized by hamartomas (benign overgrowths predominantly of a cell or tissue type that occurs normally in the organ) and hamartias (developmental abnormalities of tissue combination). Clinical manifestations include epilepsy, learning difficulties, behavioral problems, and skin lesions. Seizures can be intractable and premature death can occur from a variety of disease-associated causes. The disease is caused by variants affecting the gene represented in this entry. Lymphangioleiomyomatosis (LAM) [MIM:606690] Progressive and often fatal lung disease characterized by a diffuse proliferation of abnormal smooth muscle cells in the lungs. It affects almost exclusively young women and can occur as an isolated disorder or in association with tuberous sclerosis complex. The disease is caused by variants affecting the gene represented in this entry. Focal cortical dysplasia 2 (FCORD2) [MIM:607341] A form of focal cortical dysplasia, a malformation of cortical development that results in medically refractory epilepsy in the pediatric population and in adults. FCORD2 is a severe form, with onset usually in childhood, characterized by disrupted cortical lamination and specific cytological abnormalities. It is classified in 2 subtypes: type IIA characterized by dysmorphic neurons and lack of balloon cells; type IIB with dysmorphic neurons and balloon cells. The disease is caused by variants affecting the gene represented in this entry.
Domain organisation. The C-terminal putative coiled-coil domain is necessary for interaction with TSC2.
