PI3K/AKT signalling pathway panel containing 4 antibodies against PI 3 Kinase p85 alpha, AKT1, AKT2, AKT3 and mTOR
- Provided as a sampler panel to allow you to easily evaluate each in your required applications.
Binds to activated (phosphorylated) protein-Tyr kinases, through its SH2 domain, and acts as an adapter, mediating the association of the p110 catalytic unit to the plasma membrane. Necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. Plays an important role in signaling in response to FGFR1, FGFR2, FGFR3, FGFR4, KITLG/SCF, KIT, PDGFRA and PDGFRB. Likewise, plays a role in ITGB2 signaling (PubMed:17626883, PubMed:19805105, PubMed:7518429). Modulates the cellular response to ER stress by promoting nuclear translocation of XBP1 isoform 2 in a ER stress- and/or insulin-dependent manner during metabolic overloading in the liver and hence plays a role in glucose tolerance improvement (PubMed:20348923).

MTOR also known as mechanistic target of rapamycin is a protein kinase involved in regulating cell growth proliferation motility and survival. It has a molecular weight of approximately 289 kDa and is expressed widely across various tissues notably in areas of high cellular activity. mTOR is part of the PI3K/AKT signaling pathway where it functions as a central regulator. PI3 kinase p85 alpha is a regulatory subunit of phosphoinositide 3-kinases which plays an important role in the modulation of AKT signaling. AKT1 AKT2 and AKT3 are serine/threonine-specific protein kinases that play an important role in transmitting signals downstream of PI3K with each isoform having unique tissue-specific roles.
MTOR functions as a core component of two distinct complexes: mTORC1 and mTORC2. mTORC1 regulates protein synthesis by modulating the phosphorylation of key translational regulators while mTORC2 is involved in the regulation of the actin cytoskeleton. The PI3 kinase p85 alpha a regulatory entity mediates signaling through its interaction with catalytic subunits impacting glucose metabolism and growth. AKT being a pivotal node in cellular processes modulates glucose uptake and cell proliferation and prevents apoptosis through its activity. Collectively these proteins act to integrate signals from growth factors and nutrients to enact biological responses critical for cellular homeostasis.
MTOR PI3 kinase p85 alpha and AKT isoforms are important components of the PI3K/AKT/mTOR pathway. This pathway plays a significant role in cellular metabolism growth survival and angiogenesis. Within this context mTOR acts downstream of AKT to promote protein synthesis and cell growth. PI3K signaling initiates AKT activation which then phosphorylates various substrates including mTOR. Members of this pathway such as PTEN regulate the pathway's activity negatively modulating cellular responses and ensuring proper cell function and survival.
The dysregulation of mTOR PI3K and AKT is associated with cancer and type 2 diabetes. These proteins when aberrantly activated can lead to uncontrolled cell proliferation and tumorigenesis with mTOR being a target for rapamycin an anti-cancer drug. In type 2 diabetes insulin signaling involving the PI3K/AKT pathway becomes impaired leading to improper glucose homeostasis. The intricate relations of these proteins within these diseases highlight their potential as targets for therapeutic interventions.
