General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

Tuberin (UniProt: P49815; also known as Tuberous sclerosis 2 protein, TSC2) is encoded by the TSC2 (also known as TSC4) gene (Gene ID: 7249) in human. TSC2 is a peripheral membrane protein that serves as a tumor suppressor and is expressed in multiple tissues. In complex with TSC1 it inhibits the nutrient-mediated or growth factor-stimulated phosphorylation of S6K1 and EIF4EBP1 by negatively regulating mTORC1 signaling. It acts as a GTPase-activating protein (GAP) for the small GTPase Rheb, a direct activator of the protein kinase activity of mTORC1. In its C-terminal region it contains a highly conserved Rap-Gap domain (aa 1531-1758) that is essential for its function. TSC2 has been reported to increase the intrinsic GTPase activity of both Rap1A and Rab5 in vitro. TSC2 can undergo phosphorylation at serine 1387, 1418 or 1420. However, these phosphorylations do not affect its interaction with TSC1. It can also undergo phosphorylation at serine 939 and threonine 1462 by Akt1 induced by growth factor stimulation. When phosphorylated and activated by AMPK under conditions of low ATP:AMP ratio, it leads to negative regulation of the mTORC1 complex. AMPK-mediated phosphorylation leads to TSC1-TSC2 complex stabilization, increasing GAP activity toward Rheb and allows turning off mTORC1 signaling. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
