TSC1 forms a multi-protein complex with [[TSC2]] and [[TBC1D7]] known as the TSC complex. This complex negatively regulates [[mTORC1]] signaling by functioning as a GTPase-activating protein (GAP) for the small GTPase [[Rheb]], an essential activator of mTORC1. The TSC complex has been implicated as a [[tumor suppressor]].

Tuberous sclerosis 1 (TSC1), also known as Hamartin, is a protein that in humans is encoded by the TSC1 gene.[1]

Function

TSC1 forms a multi-protein complex with TSC2 and TBC1D7 known as the TSC complex. This complex negatively regulates mTORC1 signaling by functioning as a GTPase-activating protein (GAP) for the small GTPase Rheb, an essential activator of mTORC1. The TSC complex has been implicated as a tumor suppressor.

Clinical significance

Defects in this gene can cause tuberous sclerosis, due to a functional impairment of the TSC complex.[citation needed] Defects in TSC1 may also be a cause of focal cortical dysplasia.[citation needed] TSC1 may be involved in protecting brain neurons in the CA3 region of the hippocampus from the effects of stroke.[2]

Interactions

TSC1 has been shown to interact with:
