Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IP
Tuberous sclerosis (TSC) is an autosomal dominant disease caused by mutations in one of two tumor-suppressor genes, TSC1 and TSC2, resulting in seizures, developmental delays, behavioral problems, benign hamartomas and low grade neoplasms predominantly affecting the central nervous system, kidney, skin, lung, and heart. The dysfunction of either gene products of TSC1 and TSC2, hamartin and tuberin, respectively, may cause the appearance of these tumors. Hamartin and tuberin can interact with each other to form a cytoplasmic complex. When bound, hamartin is able to inhibit the ubiquitination of tuberin, and thus, increasing the cellular level of tuberin and inhibiting cell growth.1 Hamartin also interacts with the ezrin-radixin-moesin family of actin-binding proteins. Hamartin affects cell proliferation by deregulating the G1 phase of the cell cycle.2 Inhibition of hamartin activity results in the loss of cell adhesion. Expression studies has shown that hamartin is co-localized with tuberin in most tissues, including the liver, small and large intestines, prostate, testes, and pancreas.3 However, in the central nervous system, hamartin is mainly localized along neuronal or astrocytic processes, as opposed to tuberin, which is localized to the perinuclear region of the Purkinje cell.4 These studies indicate that hamartin may be important for astrocyte growth control.
