Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Specificity / Sensitivity
Tuberin/TSC2 Antibody detects endogenous levels of total tuberin protein independent of phosphorylation. This antibody cross-reacts with some other proteins.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal residues of human tuberin. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from NIH/3T3 cells, untreated, PDGF-treated (50 ng/ml), PDGF and wortmannin-treated (200 nM) or PDGF and rapamycin-treated (5 nM), and MCF-7 cells, untreated or IGF-1 treated for the indicated times, using Phospho-Tuberin/TSC2 (Thr1462) Antibody #3611 (upper) or Tuberin/TSC2 Antibody (lower).
Tuberin is a product of the TSC2 tumor suppressor gene and an important regulator of cell proliferation and tumor development (1). Mutations in either TSC2 or the related TSC1 (hamartin) gene cause tuberous sclerosis complex (TSC), an autosomal dominant disorder characterized by development of multiple, widespread non-malignant tumors (2). Tuberin is directly phosphorylated at Thr1462 by Akt/PKB (3). Phosphorylation at Thr1462 and Tyr1571 regulates tuberin-hamartin complexes and tuberin activity (3-5). In addition, tuberin inhibits the mammalian target of rapamycin (mTOR), which promotes inhibition of p70 S6 kinase, activation of eukaryotic initiation factor 4E binding protein 1 (4E-BP1, an inhibitor of translation initiation), and eventual inhibition of translation (3,6,7).
