Kinase, kinases changes

Mitogenic effects are mediated through MEK/MAPK (mitogen-activated protein kinase) and changes in metabolic activity mainly via PI3K.

A vertebrate homologue of the cell cycle control protein CDC37 was recently cloned and found to be an hyaladherin,62 as was a protein that copurified with the splicing factor SF2.63 An intracellular form of the HA receptor RHAMM was demonstrated to regulate erk kinase activity. Changes in function of these intracellular, depending on whether or not they have HA molecules attached, confers another layer of complexity dependent on intracellular hyaluronidase enzymes. 

Glucagon decreases cholesterol synthesis in isolated hepatocytes [131,132] apparently because it reduces the fraction of hydroxymethylglutaryl-CoA reductase in the active form [131,132], This is due to an increase in reductase kinase activity [133], However, there is no evidence that cAMP-dependent protein kinase phos-phorylates either the reductase, reductase kinase or reductase kinase kinase [134], It has been proposed that the phosphorylation state of these enzymes is indirectly controlled through changes in the activity of protein phosphatase I [132,134], This phosphatase can dephosphorylate and activate the reductase [134,135] and its activity can be controlled by a heat stable inhibitor (inhibitor 1), the activity of which is increased by cAMP-dependent phosphorylation [136,137], Since the phosphorylated forms of acetyl-CoA carboxylase, ATP-citrate lyase, pyruvate kinase, phos-phorylase, phosphorylase kinase and glycogen synthase are also substrates for protein phosphatase I [135], this mechanism could also contribute to their phosphorylation by glucagon.

As examples of applications, we present the overall accuracy of predicted ionization constants for about 50 groups in 4 proteins, changes in the average charge of bovine pancreatic trypsin inhibitor at pH 7 along a molecular dynamics trajectory, and finally, we discuss some preliminary results obtained for protein kinases and protein phosphatases.
