• Target description: Ribosomal protein S6 kinase beta-1 (UniProt: P23443; also known as EC 2.7.11.1, S6K-beta-1, S6K1, 70 kDa ribosomal protein S6 kinase 1, P70S6K1, p70-S6K 1, Ribosomal protein S6 kinase I, Serine/threonine-protein kinase 14A, p70 ribosomal S6 kinase alpha, p70 S6 kinase alpha, p70 S6K-alpha, p70 S6KA) is encoded by the RPS6KB1 (also known as STK14A) gene (Gene ID: 6198) in human. p70S6K1 is a serine/threonine-protein kinase that acts downstream of mTOR signaling in response to growth factors and nutrients to promote cell proliferation, cell growth, and cell cycle progression. It regulates protein synthesis through phosphorylation of EIF4B, RPS6, and EEF2K and contributes to cell survival by repressing the pro-apoptotic function of BAD. Upon mitogenic stimulation, phosphorylation by mTORC1 leads to its activation following dissociation from the EIF3 complex. The active p70S6K1 then phosphorylates and activates several substrates in the pre-initiation complex. It is also shown to play a role in feedback regulation of mTORC2 by mTORC1 by phosphorylating RICTOR, which results in the inhibition of mTORC2 and Akt1 signaling. The protein kinase domain of p70S6K1 is localized to amino acids 91-352 and the autoinhibitory domain is localized to amino acids 424-525. The autoinhibitory domain blocks phosphorylation within the AGC-kinase C-terminal domain and the activation loop. Its activation requires multiple phosphorylation events on serine/threonine residues. Phosphorylation of multiple sites in the autoinhibitory domain disrupts the autoinhibitory mechanism and allows phosphorylation of threonine 252 by PDPK1. The active conformation of the kinase is stabilized by phosphorylation of sites (Thr 252; Ser 394; and Thr 412) located in the kinase domain activation loop. It also contains a TOR signaling (TOS) motif (aa 28-32) that is essential for its activation by mTORC1. Five isoforms of p70S6K1 have been described that are produced by alternative splicing and alternative initiation. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
• Reconstitution: 300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
