Tuberin, a product of the tumor suppressor gene TSC2, is important in regulating cell proliferation and tumor development. Mutation in either TSC1or TSC2 is responsible for tuberous sclerosis complex (TSC), an autosomal dominant disorder. Tuberin is directly phosphorylated at Thr1462 by Akt/PKB. Phosphorylation at Thr1462 and Tyr1571 regulates tuberin-hamartin complexes and tuberin activity. Additionally, tuberin inhibits the mammalian target of rapamycin (mTOR), resulting in inhibition of p70 S6 kinase and activation of eukaryotic initiation factor 4E binding protein 1 (4E-BP1, an inhibitor of translation initiation) and, thus, inhibition of translation. p38-activated kinase MK2 (MAPKAPK-2) phosphorylates Ser1254 of tuberin, and thus augments the interaction between tuberin and 14-3-3.
