I have a '5 Way Reflector' that I want to use in my photography, which includes the following 5 options: 1  Gold reflective. 2  Silver reflective. 3  Gold/silver alternating pattern reflective. 4  White. 5  Scrim/opaque. 6  Black*.
The endoplasmic reticulum (ER) resident PKR-like kinase (PERK) is necessary for Akt activation in response to ER stress. We demonstrate that PERK harbors intrinsic lipid kinase, favoring diacylglycerol (DAG) as a substrate and generating phosphatidic acid (PA). This activity of PERK correlates with activation of mTOR and phosphorylation of Akt on Ser473. PERK lipid kinase activity is regulated in a phosphatidylinositol 3-kinase (PI3K) p85Î±-dependent manner. Moreover, PERK activity is essential during adipocyte differentiation.
Several kinds of kinases have closely-associated proteins that regulate kinase activity. The best known are the cyclins, which act as regulators of the cell cycle CDK (Cyclin Dependent Kinase) kinases. Others include PKA ((Protein Kinase A), modulated by cAMP, PKG by cGMP, PKA by AKAP proteins, and many more.
