|Precautions||TSC1/Hamartin Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||In complex with TSC2, inhibits the nutrient-mediated or growth factor-stimulated phosphorylation of S6K1 and EIF4EBP1 by negatively regulating mTORC1 signaling (PubMed:12271141, PubMed:28215400). Seems not to be required for TSC2 GAP activity towards RHEB (PubMed:15340059). Implicated as a tumor suppressor. Involved in microtubule-mediated protein transport, but this seems to be due to unregulated mTOR signaling (By similarity). Acts as a co-chaperone for HSP90AA1 facilitating HSP90AA1 chaperoning of protein clients such as kinases, TSC2 and glucocorticoid receptor NR3C1 (PubMed:29127155). Increases ATP binding to HSP90AA1 and inhibits HSP90AA1 ATPase activity (PubMed:29127155). Competes with the activating co-chaperone AHSA1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins (PubMed:29127155). Recruits TSC2 to HSP90AA1 and stabilizes TSC2 by preventing the interaction between TSC2 and ubiquitin ligase HERC1 (PubMed:16464865, PubMed:29127155).|

Tuberous sclerosis complexes-1 (TSC1 also known as Hamartin) is a tumor suppressor that form a complex with TSC2 (Tuberin). This complex is known to control various cellular functions including cell cycle, endocytosis, adhesion, and transcription (1). The TSC1/TSC2 complex inhibits phosphorylation of S6kinase and 4E-BP1 through inactivation of mTOR (2). Recently it has been shown that TSC1/Hamartin is localized to the centrosome and negatively regulates Plk1 implicating TSC1/hamartin to the regulation of centrosome duplication (3). Tuberous sclerosis (TSC), an autosomal dominant disorder that affects 1 in 6000 individuals, is caused by a mutation in either the TSC1 or TSC2 tumor suppressor gene.
