Elucidation of the involvement of protein kinase C subtypes in several diseases is an important challenge for the future development of new drug targets. We previously identified the PKI55 protein, which acts as a protein kinase C modulator, establishing a feedback loop of inhibition. The PKI55 protein is able to penetrate the cell membrane of activated(More)
PKI55 protein, coded by the recently identified KI55 gene [R. Selvatici, E. Melloni, M. Ferrati, C. Piubello, F.C. Marincola, E. Gandini, J. Mol. Evol. 57 (2003) 131-139] is synthesized following protein kinase C (PKC) activation and acts as a PKC modulator, establishing a feedback loop of inhibition. In this work, PKI55 was found to inhibit recombinant(More)
A variety of harmful stimuli, among them energy depletion occurring during transient brain ischemia, are thought to unbalance protein kinase cascades, ultimately leading to neuronal damage. In superfused, electrically stimulated rat cerebral cortex slices, chemical ischemia (CI) was induced by a 5-min treatment with the mitochondrial toxin, sodium azide (10(More)
The aim of the current study was to characterize the effects of chemical ischemia and reperfusion at the transductional level in the brain. Protein kinase C isoforms (alpha, beta(1), beta(2), gamma, delta and epsilon) total levels and their distribution in the particulate and cytosolic compartments were investigated in superfused rat cerebral cortex slices:(More)
