Notes
AKT 1/2/3 pS473 + AKT 1/2/3 Total (ab253299) is a single-wash 90 min sandwich ELISA designed for the semi-quantitative measurement of total AKT 1/2/3 pS473 + AKT 1/2/3 total protein in human and mouse cell lysates. It uses our proprietary SimpleStep ELISA® technology. Semi-quantitate AKT 1/2/3 pS473 + AKT 1/2/3 total with 1 μg/mL sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpeStep ELISA® kits.
AKT isoforms belong to a conserved family of serine/threonine protein kinases. AKT plays a central role in cell survival and inhibiting apoptosis, by phosphorylating and inactivating several targets. AKT is activated by insulin and various other agonists, which promote transport to the plasma membrane, where the activation loop of AKT is phosphorylated at Thr308 by PDK1. The carboxy terminus is phosphorylated at Ser473 by mammalian target of rapamycin complex 2 (TORC2).
AKT substrates include Bad, forkhead transcription factors, and caspase-9. Another vital AKT function is the regulation of glycogen synthesis through phosphorylation of GSK-3. AKT phosphorylation also prevents GSK-3β mediated phosphorylation and degradation of cyclin D1, and negatively regulates the cyclin dependent kinase inhibitors p27 Kip and p21 Waf1/CIP1. AKT also plays a critical role in the regulation of TORC1 and tuberin (TSC2).

- Activity summary
AKT 1/2/3 also known as protein kinase B (PKB) consists of three isoforms; AKT1 AKT2 and AKT3. These proteins are serine/threonine-specific kinases with a molecular weight around 56 kDa. They are phosphorylated at Ser473 which regulates their activity. AKT proteins are expressed ubiquitously but the expression levels can vary across different tissues. AKT1 is primarily found in most tissues AKT2 is mostly present in insulin-responsive tissues like liver muscle and adipose tissue while AKT3 is largely detected in the brain.
- Biological function summary
AKT proteins perform critical roles in key signaling pathways such as the PI3K/AKT pathway which is important for cellular processes like growth proliferation and survival. AKT activation requires phosphorylation at two sites: Thr308 in the activation loop and Ser473 in the hydrophobic motif. These kinases attend a complex signaling network involving direct phosphorylation of multiple downstream targets influencing numerous cellular processes. AKT1 AKT2 and AKT3 might have overlapping as well as unique functions in vivo reflecting their different tissue distributions and substrate specificities.
- Pathways
AKT proteins are central components of the insulin signaling pathway and the PI3K/AKT/mTOR pathway. These pathways play essential roles in regulating metabolism cell survival and growth. AKT interacts with various other proteins such as mTOR and FOXO transcription factors. In the PI3K/AKT/mTOR pathway AKT acts downstream of PI3K to activate or inhibit targets that regulate protein synthesis metabolism and apoptosis.
- Associated diseases and disorders
AKT dysregulation is associated with many cancers and metabolic diseases like diabetes. Aberrant activation of the PI3K/AKT/mTOR pathway contributes to oncogenesis as it promotes cell survival and proliferation. In metabolic diseases altered AKT activity affects insulin signaling leading to insulin resistance and type 2 diabetes. AKT is also linked with proteins such as PTEN which serve as tumor suppressors by inhibiting the PI3K/AKT pathway showing the importance of balancing AKT activity for normal cellular function.
