WebJan 16, 1998 · Recombinant XRCC4 is phosphorylated during expression in insect cells. XRCC4 phosphorylation in Sf9 cells occurs on serine, threonine, and tyrosine residues. We also investigated whether XRCC4 interacts with the other factor known to be requisite for both V(D)J recombination and DSBR, the DNA-dependent protein kinase. We report that … WebSep 29, 2010 · Kinases generally fall into two categories: they will either phosphorylate the smaller serine and/or threonine- usually interchangeably- or they will phosphorylate the bulkier aromatic tyrosine. They are thus appropriately named the protein serine/threonine kinases (PSTKs) and protein tyrosine kinases (PTKs).

WebMature (i.e., phosphorylated) PKC is typically localized to the cytosol where it bounces on and off the membrane by diffusion-controlled mechanisms (although it is often scaffolded at specific locations, thus, increasing the local concentration for more … WebThe control of glycogen synthase is a key step in regulating glycogen metabolism and glucose storage. Glycogen synthase is directly regulated by glycogen synthase kinase 3 (GSK-3), AMPK, protein kinase A (PKA), and casein kinase 2 (CK2). Each of these protein kinases lead to phosphorylated and catalytically inactive glycogen synthase. The ... WebHormone-sensitive lipase (EC 3.1.1.79; HSL) is a key enzyme in the mobilization of fatty acids from stored triacylglycerols. HSL activity is controlled by phosphorylation of at least four serines. In rat HSL, Ser563, Ser659 and Ser660 are phosphorylated by protein kinase A (PKA) in vitro as well as … how much is extra first class postage
