We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

Tuberin also known as TSC2 is a tumor suppressor protein with a role in cell growth regulation. It has a molecular mass of approximately 200 kDa. This protein forms a critical component of the TSC1-TSC2 complex and is expressed widely in various tissues including the brain kidney heart and skin. Tuberin possesses GTPase-activating protein (GAP) activity targeting specifically the small GTPase protein Rheb which leads to inhibition of the mammalian target of rapamycin complex 1 (mTORC1).
Biological function summary

Tuberin helps control cell size and proliferation. It does this by modulating the mTOR signaling pathway. This modulation is essential for maintaining cellular homeostasis and energy balance particularly under conditions of nutrient scarcity. Tuberin as part of the TSC1-TSC2 complex also influences cell cycle progression and protein synthesis. Its functions are vital in preventing abnormal cell growth and division which is particularly important in organs where rapid cell turnover occurs.

Pathways

Tuberin plays a central role in the mTOR signaling pathway which affects cell growth autophagy and metabolism. It directly interacts with hamartin (TSC1) to form the TSC1-TSC2 complex which regulates Rheb activity. By inhibiting Rheb Tuberin helps control the mTORC1 pathway linking it to signals such as growth factors stress energy status and amino acid availability. This coordination is important for the proper balance between cell growth and catabolism.

Tuberin is mainly associated with Tuberous Sclerosis Complex (TSC) and certain forms of epilepsy. Mutations or loss of function in TSC2 can lead to benign tumor formations in multiple organs including the brain kidneys and skin. It is also implicated in the development of lymphangioleiomyomatosis (LAM) a rare lung disease. Tuberin's interaction with mTORC1 highlights its connection with these conditions as hyperactivation of the mTOR pathway contributes significantly to the pathogenesis.

Target data

Catalytic component of the TSC-TBC complex, a multiprotein complex that acts as a negative regulator of the canonical mTORC1 complex, an evolutionarily conserved central nutrient sensor that stimulates anabolic reactions and macromolecule biosynthesis to promote cellular biomass generation and growth (PubMed : 12172553, PubMed : 12271141, PubMed : 12842888, PubMed : 12906785, PubMed : 15340059, PubMed : 22819219, PubMed : 24529379, PubMed : 28215400, PubMed : 33436626, PubMed : 35772404). Within the TSC-TBC complex, TSC2 acts as a GTPase-activating protein (GAP) for the small GTPase RHEB, a direct activator of the protein kinase activity of mTORC1 (PubMed : 12172553, PubMed : 12820960, PubMed : 12842888, PubMed : 12906785, PubMed : 15340059, PubMed : 22819219, PubMed : 24529379, PubMed : 33436626). In absence of nutrients, the TSC-TBC complex inhibits mTORC1, thereby preventing phosphorylation of ribosomal protein S6 kinase (RPS6KB1 and RPS6KB2) and EIF4EBP1 (4E-BP1) by the mTORC1 signaling (PubMed : 12172553, PubMed : 12271141, PubMed : 12842888, PubMed : 12906785, PubMed : 22819219, PubMed : 24529379, PubMed : 28215400, PubMed : 35772404). The TSC-TBC complex is inactivated in response to nutrients, relieving inhibition of mTORC1 (PubMed : 12172553, PubMed : 24529379). Involved in microtubule-mediated protein transport via its ability to regulate mTORC1 signaling (By similarity). Also stimulates the intrinsic GTPase activity of the Ras-related proteins RAP1A and RAB5 (By similarity).
