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.
The CDKs directly involved in the regulation of the cell cycle associate with small, 9- to 13-kiloDalton proteins called Suk1 or Cks. These proteins are required for CDK function, but their precise role is unknown. Cks1 binds the carboxy lobe of the CDK, and recognizes phosphorylated residues.he structure of human Cdk2 revealed that CDKs have a modified ATP-binding site that can be regulated by cyclin binding. Phosphorylation by CDK-activating kinase (CAK) at Thr 161 on the T-loop increases the complex activity.
