THE EFFECT OF THEOPHYLLINE ON THE KINETICS OF cAMP-DEPENDENT PROTEIN KINASE CATALYTIC SUBUNIT, cAMP, PROTEIN KINASE INHIBITOR AND THEIR RELATIONSHIP IN LUNG TISSUE
We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...
متن کاملProtein kinase CK2.
Protein kinase CK2 is a ubiquitous protein kinase responsible for the phosphorylation of Ser and Thr residues specified by acidic side chains in many proteins, including several key enzymes, growth factor receptors, transcription factors and cytoskeletal proteins. The holoenzyme is composed of two catalytic and two regulatory subunits, the latter having antagonistic roles. CK2 is constitutively...
متن کاملResorufin: a lead for a new protein kinase CK2 inhibitor.
Screening a natural compound library led to the identification of resorufin as a highly selective and potent inhibitor of protein kinase CK2. Out of 52 kinases tested, only CK2 was inhibited, in contrast to emodin, a structurally related, known CK2 inhibitor that, in addition to CK2, inhibited ten other kinases by 90%. The IC50 values determined for the CK2 holoenzymes were 1.5 mol/l and for th...
متن کاملThe selectivity of inhibitors of protein kinase CK2: an update.
CK2 (casein kinase 2) is a very pleiotropic serine/threonine protein kinase whose abnormally high constitutive activity has often been correlated to pathological conditions with special reference to neoplasia. The two most widely used cell permeable CK2 inhibitors, TBB (4,5,6,7-tetrabromo-1H-benzotriazole) and DMAT (2-dimethylamino-4,5,6,7-tetrabromo-1H-benzimidazole), are marketed as quite spe...
متن کاملThe Link between Protein Kinase CK2 and Atypical Kinase Rio1
The atypical kinase Rio1 is widespread in many organisms, ranging from Archaebacteria to humans, and is an essential factor in ribosome biogenesis. Little is known about the protein substrates of the enzyme and small-molecule inhibitors of the kinase. Protein kinase CK2 was the first interaction partner of Rio1, identified in yeast cells. The enzyme from various sources undergoes CK2-mediated p...
