The three isoforms of Akt share a higher level of sequence homology and structural similarity. The current model shows that Akt is activated through the phosphatidylinositol 3 kinase pathway on growth factor stimulation. The products of PI3K, especially phosphatidyl inositol triphosphate, bind to the Pleckstrin homology Adriamycin Topoisomerase inhibitor domain of Akt and goal Akt to the plasma membrane where it’s phosphorylated on two key residues: Thr308 in the activation loop by PDK1 and Ser473 in the hydrophobic motif of the C terminal tail by putative PDK2. Proposed candidates of PDK2 contain PDK1, integrin associated kinase, Akt it self, DNA PKcs, and lately, the target of rapamycin rictor complex. Phosphorylation on both Thr308 and Ser473 is needed for complete activation of Akt. Several substrates for Akt have now been discovered, including caspase 9, Bad, forkhead transcription facets, I?B kinase kinase, glycogen synthase kinase 3, MDM2, p21cip1/WAF1, TSC2, and the like. Among these, caspase 9, Bad, and forkhead transcription facets help Ribonucleic acid (RNA) apoptosis, and the phosphorylation by Akt abolishes their proapoptotic activities. PI3K Akt transduces mitogenic signals from growth facets and promotes G1/S transition. Through multiple things, Akt downregulates p27, an essential Cdk chemical that prevents cells in lateG1 until cells are prepared for DNA synthesis. Akt pathway also regulates the transition at G2/M. Often PI3K inhibitors or the lack of Akt in Akt1 null ES cells were reported to produce a delay in G2/M change. The Akt pathway is shown to determine mitotic entry in addition to its mitogenic functions at the G1/S transition. Inhibition of PI3K in a delay in the development through G2/M, which is often rescued by overexpressing Akt. PTEN null ES cells were shown to transportation faster through the cycle. Crizotinib ALK inhibitor Overexpressing a dominant negative mutant of Akt also arrests cells in G2/M. Finally, PI3K Akt path regulates mitotic entry through controlling the timing of Cdc2 service. Wee1 and Myt1 are two kinases that phosphorylate Cdc2 at Thr14/ Tyr15 and inhibit Cdc2 kinase activity. Akt phosphorylates and downregulates Myt1 at the border. Moreover, Akt was shown to phosphorylateWEE1Hu at Ser642, which often offers the binding site for 14. That 14 3 joining translocates WEE1Hu to the cytoplasm and, therefore, prevents its inhibitory phosphorylation on Cdc2. Akt also stops Plk1 wreckage through CHFR and promotes mitotic entry under normal circumstances and after DNA damage. Aurora kinases are serine/threonine kinases that regulate mitotic activities, which range from centrosome maturation, mitotic spindle formation, chromosome segregation to cytokinesis. The three members of Aurora kinase family in metazoans discuss substantial structure and sequence similarities. However, they show different localizations and functions during mitosis. Aurora A localizes to centrosomes and is important for maturation and centrosome duplication.
