This domain family is found in eukaryotes, and is typically between 117 and 132 amino acids in length. PRAS domain family is found in eukaryotes, and is typically between 117 and 132 amino acids in length. It is a proline-rich family that can be phosphorylated by AKT, and in the phosphorylated state binds to 14-3-3. The AKT signalling pathway contributes to regulation of apoptosis after a variety of cell death stimuli, and PRAS is found to be a substrate. PRAS plays an important role in regulating cell survival downstream of the PI3-K/Akt pathway after re-perfusion injury after transient focal cerebral ischemia. Copper/zinc-SOD (SOD1), a cytosolic isoenzyme of superoxide dismutase, SOD, is highly protective against ischemia and re-perfusion injury after transient focal cerebral ischemia, and SOD1 thus contributes to the inhibition of direct oxidation of PRAS and the activation of its signalling pathway. PRAS is also a mTOR binding partner, and PRAS phosphorylation by AKT and its association with 14-3-3, a cytosolic anchor protein, are crucial for insulin to stimulate mTOR (mammalian target of rapamycin).
