Funkcija

uredi

TSC1 funkcionira kao košaperon koji inhibira aktivnost šaperonskih ATPaza šaperona Hsp90 (protein toplotnog šoka-90) i usporava njegov ciklus praćenja. Tsc1 funkcionira kao posrednik Hsp90 u praćenju klijenata kinaze i nekinaze, uključujući Tsc2, čime se sprječava njihova sveprisutna i degradacija u proteasomu.[7] TSC1, TSC2 i TBC1D7 je kompleks više proteina poznat i kao kompleks TSC. Ovaj kompleks negativno regulira signalizaciju mTORC1, funkcionirajući kao protein koji aktivira GTPazu (GAP) za malu GTPazu Rheb, bitan aktivator mTORC1. TSC kompleks je uključen u supresiju tumora.

Klinički značaj

uredi

Defekti ovog gena mogu uzrokovati tuberoznu sklerozu, zbog funkcionalnog oštećenja kompleksa TSC. Oni u TSC1 mogu biti i uzrok fokusne korteksne displazije . TSC1 može biti uključen u zaštitu moždanih neurona u CA3 regiji hipokampusa od posljedica moždanog udara.[8]
