DescriptionAnti-Harmartin (TSC1) Antibody
Alternate Names
  • Tuberous sclerosis 1 protein
  • tuberous sclerosis 1
  • tumor suppressor
Background InformationHarmartin is the gene product of tuberous sclerosis-1 (TSC1). It is thought to have a tumor suppression function and also augments the expression of the TSC2 product tuberin by inhibiting its ubiquitination.

UniProt Number
UniProt SummaryFUNCTION: 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.
SUBUNIT STRUCTURE: Interacts with TSC2, leading to stabilize TSC2. In the absence of TSC2, TSC1 self-aggregates. Interacts with DOCK7. SUBCELLULAR LOCATION: Cytoplasm. Membrane; Peripheral membrane protein. Note: At steady state found in association with membranes.
TISSUE SPECIFICITY: Highly expressed in skeletal muscle, followed by heart, brain, placenta, pancreas, lung, liver and kidney. Also expressed in embryonic kidney cells.
DOMAIN: The C-terminal putative coiled-coil domain is necessary for interaction with TSC2.
PTM: Phosphorylation at Ser-505 does not affect interaction with TSC2. Phosphorylated upon DNA damage, probably by ATM or ATR.
INVOLVEMENT IN DISEASE: Defects in TSC1 are the cause of tuberous sclerosis complex (TSC) [MIM:191100]. The molecular basis of TSC is a functional impairment of the hamartin-tuberin complex. TSC is an autosomal dominant multi-system disorder that affects especially the brain, kidneys, heart, and skin. TSC 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 symptoms can range from benign hypopigmented macules of the skin to profound mental retardation with intractable seizures to premature death from a variety of disease-associated causes.
Defects in TSC1 may be a cause of focal cortical dysplasia of Taylor balloon cell type (FCDBC) [MIM:607341]. FCDBC is a subtype of cortical displasias 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.
