Protein Structure

|
Function |
In complex with TSC2, inhibits the nutrient-mediated or growth factor-stimulated phosphorylation of S6K1 and EIF4EBP1 by negatively regulating mTORC1 signaling. Seems not to be required for TSC2 GAP activity towards RHEB. Implicated as a tumor suppressor. Involved in microtubule-mediated protein transport, but this seems to be due to unregulated mTOR signaling. {ECO:0000269PubMed:12271141, ECO:0000269PubMed:15340059}.

Disease Associations |
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. {ECO:0000269PubMed:10227394, ECO:0000269PubMed:10533069, ECO:0000269PubMed:10570911, ECO:0000269PubMed:10874311, ECO:0000269PubMed:18830229, ECO:0000269PubMed:22161988, ECO:0000269PubMed:9328481}. Note=The disease is caused by mutations affecting the gene represented in this entry.Focal cortical dysplasia of Taylor balloon cell type (FCDBC) [MIM:607341]: Subtype of cortical dysplasias linked to chronic intractable epilepsy. Cortical dysplasias display a broad spectrum of structural changes, which appear to result from changes in proliferation, migration, differentiation, and apoptosis of neuronal precursors and neurons during cortical development. {ECO:0000269PubMed:12112044}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
