Identification of casein kinase 1, casein kinase 2, and cAMP-dependent protein kinase-like activities in Trypanosoma evansi.
Trypanosoma evansi contains protein kinases capable of phosphorylating endogenous substrates with apparent molecular masses in the range between 20 and 205 kDa. The major phosphopolypeptide band, pp55, was predominantly localized in the particulate fraction. Anti-alpha and anti-beta tubulin monoclonal antibodies recognized pp55 by Western blot analyses, suggesting that this band corresponds to ...
متن کاملStructural and functional studies of casein kinase I-like protein from rice.
Casein kinase I (CKI) is a protein serine/threonine kinase that is highly conserved from plants to animals. It performs various functions in both the cytoplasm and nucleus, such as DNA repair, cell cycle, cytokinesis, vesicular trafficking, morphogenesis and circadian rhythm. CKI proteins contain a highly conserved kinase domain responsible for catalytic activity at the N-terminus and a highly ...
متن کاملThe proposed plant connexin is a protein kinase-like protein.
Functional analogies appear to exist between gap junctions, the structures involved in maintaining conductivity between contacting animal cells, and plant plasmodesmata (see papers collected in Robards et al., 1990, for state-of-the-art discussion). These include similar behavior with regard to tracer dyes, similar electrical properties, and similar mode of down regulation by effectors of prote...
متن کاملBudding and fission yeast casein kinase I isoforms have dual-specificity protein kinase activity.
We have examined the activity and substrate specificity of the Saccharomyces cerevisiae Hrr25p and the Schizosaccharomyces pombe Hhp1, Hhp2, and Cki1 protein kinase isoforms. These four gene products are isotypes of casein kinase I (CKI), and the sequence of these protein kinases predicts that they are protein serine/threonine kinases. However, each of these four protein kinases, when expressed...
متن کاملPea DNA topoisomerase I is phosphorylated and stimulated by casein kinase 2 and protein kinase C.
DNA topoisomerase I catalyzes the relaxation of superhelical DNA tension and is vital for DNA metabolism; therefore, it is essential for growth and development of plants. Here, we have studied the phosphorylation-dependent regulation of topoisomerase I from pea (Pisum sativum). The purified enzyme did not show autophosphorylation but was phosphorylated in an Mg(2+)-dependent manner by endogenou...
