Thrombin-induced endothelial cell barrier dysfunction is tightly linked to Ca(2+)-dependent cytoskeletal protein reorganization. In this study, we found that thrombin increased Ca(2+)/calmodulin-dependent protein kinase II (CaM kinase II) activities in a Ca(2+)- and time-dependent manner in bovine pulmonary endothelium with maximal activity at 5 min. Pretreatment with KN-93, a specific CaM kina...
Shikimate kinase II was purified to near homogeneity from an Escherichia coli strain which overproduced the enzyme. The apparent Km of this isoenzyme for shikimate was 200 microM, and for ATP it was 160 microM. The Km for shikimate is approximately 100-fold lower than the Km of shikimate kinase I, suggesting that shikimate kinase II is the isoenzyme normally functioning in aromatic biosynthesis...
BACKGROUND AND PURPOSE Evidence linking changes in calcium/calmodulin-dependent protein kinase II activity with ischemic cell death has been reported in animal models of global ischemia. The purpose of this study was to delineate the course of these changes after focal ischemia and to clarify the relation of changes in activity of calcium/calmodulin-dependent protein kinase II to the process of...
It is well known that angiotensin II (Ang II) is implicated in the phenotypic modulation and hypertrophy of vascular smooth muscle cells (VSMCs). To study the mechanisms by which Ang II contributes to the pathological changes of VSMCs, we examined whether Ang II stimulated myocyte enhancer factor 2 (MEF2)- and calcineurin/nuclear factor of activated T cell (NFAT)-dependent transcriptional activ...
Cyclic AMP (cAMP) and its action by way of cAMP-dependent protein kinase is important for sperm motility. Previous studies on germ cells have demonstrated a selective decrease in the amount of type I cAMP-dependent protein kinase during spermatid development, and that type II was the major form present in elongating spermatids and in mature sperm. This would indicate activation of a gene in hap...
We have expressed the rat brain Ca2+/calmodulin (CaM)-dependent protein kinase type IV in insect cells. The recombinant enzyme is produced as a single polypeptide that migrates on SDS-polyacrylamide gel electrophoresis at 61 kDa. Recombinant CaM kinase IV undergoes slow CaM-dependent autophosphorylation. The autophosphorylation of CaM kinase IV occurs on serine residues but is not accompanied b...
