Product Specifications

Immunogen

AKT1 [p Thr308] Antibody (18F3.H11) was produced by repeated immunizations with a synthetic peptide corresponding to residues surrounding T308 of human AKT11 protein. (Uniprot: P31749)

Reactivity Notes

A BLAST analysis was used to suggest cross-reactivity with AKT1 pT308 from most vertebrate species sources based on 100% homology with the immunizing sequence. Cross-reactivity with AKT1 from other sources has not been determined. Cross-reactivity with AKT2 and AKT3 will likely occur.

Modification

p Thr308

Specificity

This antibody is specific for human and mouse AKT protein phosphorylated at T308. A BLAST analysis was used to suggest cross-reactivity with AKT pT308 from most vertebrate species sources based on 100% homology with the immunizing sequence. Cross-reactivity with AKT from other sources has not been determined. Cross-reactivity with AKT2 and AKT3 will likely occur.

Application
Recommended Usage

ELISA

1:20000

Flow Cytometry

1:1:10 - 1:1000

Immunocytochemistry/ Immunofluorescence

1:10-1:500

Immunohistochemistry

Application Notes
This product is tested for ELISA, immunohistochemistry, immunoprecipitation and western blotting. Expect a band approximately 56 kDa in size corresponding to phosphorylated AKT protein by western blotting in the appropriate cell lysate or extract. This phospho-specific monoclonal antibody reacts with human and mouse AKT pT308 and shows minimal reactivity by ELISA against the non-phosphorylated form of the immunizing peptide. Specific conditions for reactivity should be optimized by the end user. Use formalin-fixed paraffin-embedded sections for immunohistochemistry. No pre-treatment of sample is required.

Background: Akt1

AKT (also known as protein kinase B (PKB) and RAC (related to A and C kinases)) is a critical intracellular serine/threonine kinase that translates signals from extracellular stimuli including growth factors, cytokines and neurotransmitters (1). AKT signaling plays critical roles in cell growth, proliferation, survival and differentiation (1). It is also involved in organogenesis, angiogenesis and metabolism. Three mammalian AKT isoforms have been identified. The AKT pathway can be activated by any of the three members who share a high level of protein homology but are independently encoded by AKT1 (PKB alpha; 14q32.32), AKT2 (PKB beta; 19q13.2), or AKT3 (PKB gamma; 1q44) (1, 2). Each AKT family member contains an N-terminal pleckstrin homology (PH) domain, a central kinase domain, and a C-terminal regulatory domain. AKT mediates many of the downstream events of phosphatidylinositol 3-kinase (PI3-K), a lipid kinase activated by growth factors, cytokines and insulin. PI3-K recruits AKT to the membrane, where it is activated by PDK1 phosphorylation. AKT has two main phosphorylation sites (Ser473 and Thr308, predicted molecular weight 56 kDa) (3, 4). Once phosphorylated, AKT dissociates from the membrane and phosphorylates targets in the cytoplasm and the cell nucleus including mammalian target of rapamycin (mTOR).

The main function of AKT is to control inhibition of apoptosis and promote cell proliferation. Survival factors can activate AKT Ser473 and Thr308 phosphorylation sites in a transcription-independent manner, resulting in the inactivation of apoptotic signaling transduction through the tumor suppressor PTEN, an antagonist to PI3-K (5). PTEN exerts enzymatic activity as a phosphatidylinositol-3,4,5-trisphosphate (PIP3) phosphatase, opposing PI3K activity by decreasing availability of PIP3 to proliferating cells, leading to overexpression and inappropriate activation of AKT noted in many types of cancer.

AKT1 function has been linked to overall physiological growth and function (2). AKT1 has been correlated with proteus syndrome, a rare disorder characterized by overgrowth of various tissues caused by a mosaic variant in the AKT1 gene in humans.

AKT2 is strongly correlated with Type II diabetes, including phenotypes of insulin resistance, hyperglycemia and atherosclerosis (2, 6).

The function of AKT3 is specifically associated to brain development, where disruptions to AKT3 are correlated with microcephaly, hemimegalencephaly, megalencephaly and intellectual disabilities (2).
