Binding to protein kinase B, an intracellular kinase that is important in regulating glucose metabolism. [GOC:jl, http://www.heartandmetabolism.org/]
Protein kinase B (PKB), also known as Akt, is a serine/threonine-specific protein kinase that plays a critical role in a variety of cellular processes, including cell survival, growth, proliferation, and metabolism. PKB binding is a complex process involving multiple interactions and regulatory mechanisms.
One of the primary molecular functions of PKB binding is the activation of PKB. This occurs when PKB is recruited to the plasma membrane by the binding of phosphatidylinositol (3,4,5)-trisphosphate (PIP3), a lipid second messenger generated by phosphoinositide 3-kinase (PI3K).
The binding of PIP3 to the PH domain of PKB triggers a conformational change in the protein, exposing the catalytic domain and allowing for phosphorylation of PKB at Thr308 and Ser473 by upstream kinases, such as phosphoinositide-dependent protein kinase 1 (PDK1) and mammalian target of rapamycin complex 2 (mTORC2), respectively.
Phosphorylation at these sites fully activates PKB, which then phosphorylates a wide range of downstream substrates, including transcription factors, metabolic enzymes, and other signaling proteins.
These phosphorylation events can lead to a variety of cellular responses, including increased glucose uptake, protein synthesis, and cell survival.
PKB binding is also involved in the regulation of other signaling pathways, including the MAPK pathway, the Wnt pathway, and the Hippo pathway.
The precise mechanisms by which PKB binding regulates these pathways are still being investigated, but it is likely that PKB binding can modulate the activity of specific components of these pathways, leading to changes in their downstream signaling outputs.
Overall, PKB binding is a crucial event that plays a central role in coordinating a variety of cellular processes. The precise molecular function of PKB binding is complex and multifaceted, involving interactions with a wide range of proteins and lipids and leading to diverse cellular responses.
