Descriptions

Akt is a serine/threonine kinase that belongs to a group of proteins called the AGC superfamily. It is involved in various biological responses through the phosphatidylinositol 3-kinase (PI3K) signal transduction pathway. Akt2, in particular, is regulated by different regions of the protein.<br>The N-terminal PH domain of Akt2 plays a regulatory role in its activation. Phosphorylation of Ser474 in the C-terminal regulatory domain is also necessary for full activation of Akt2. These modifications help activate the kinase and enable it to carry out its functions.<br>The linker region between the N-lobe and C-lobe of Akt2 occupies the ATP binding site. Additionally, the activation loop within Akt2 aids in autoinhibition by blocking the binding of peptide substrates, while still allowing access to the ATP binding site.

Functions

Description
EC Number 2.7.11.1 Protein-serine/threonine kinases
Subcellular Localization
  • Cytoplasm
  • Nucleus
  • Cell membrane
  • Nucleus after activation by integrin-linked protein kinase 1 (ILK1)
  • Nuclear translocation is enhanced by interaction with TCL1A (By similarity)
  • Phosphorylation on Tyr-176 by TNK2 results in its localization to the cell membrane where it is targeted for further phosphorylations on Thr-308 and Ser-473 leading to its activation and the activated form translocates to the nucleus
  • Colocalizes with WDFY2 in intracellular vesicles (By similarity)

3 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

6 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
calmodulin binding Binding to calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
potassium channel activator activity Binds to and increases the activity of a potassium channel, resulting in its opening.
protein kinase activity Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions

24 GO annotations of biological process

Name Definition
apoptotic process A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
cellular response to epidermal growth factor stimulus Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an epidermal growth factor stimulus.
cellular response to insulin stimulus Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an insulin stimulus. Insulin is a polypeptide hormone produced by the islets of Langerhans of the pancreas in mammals, and by the homologous organs of other organisms.
glucose metabolic process The chemical reactions and pathways involving glucose, the aldohexose gluco-hexose. D-glucose is dextrorotatory and is sometimes known as dextrose; it is an important source of energy for living organisms and is found free as well as combined in homo- and hetero-oligosaccharides and polysaccharides.
glycogen biosynthetic process The chemical reactions and pathways resulting in the formation of glycogen, a polydisperse, highly branched glucan composed of chains of D-glucose residues.
negative regulation of cilium assembly Any process that stops, prevents or reduces the frequency, rate or extent of cilium assembly.
negative regulation of cysteine-type endopeptidase activity involved in apoptotic process Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process.
negative regulation of protein localization to lysosome Any process that stops, prevents or reduces the frequency, rate or extent of protein localization to lysosome.
negative regulation of release of cytochrome c from mitochondria Any process that decreases the rate, frequency or extent of release of cytochrome c from mitochondria, the process in which cytochrome c is enabled to move from the mitochondrial intermembrane space into the cytosol, which is an early step in apoptosis and leads to caspase activation.
nervous system development The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.
organic substance transport The directed movement of organic substances into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore. An organic substance is a molecular entity that contains carbon.
