A calcium/calmodulin-binding serine/threonine protein kinase homologous to the mammalian type II calcium/calmodulin-dependent protein kinase is expressed in plant cells.

چکیده
cDNA fragments corresponding to an apple (Malus domestica [L.] Borkh) calmodulin-binding polypeptide have been isolated and characterized. The protein encoded by this messenger contains a serine/threonine protein kinase catalytic domain followed by a calcium/calmodulin-binding regulatory domain, both exhibiting significant sequence similarities to the corresponding regions of the mammalian calcium/calmodulin-dependent protein kinase II subunits. These results confirm a potential regulatory role for calmodulin in phosphorylation-mediated signal transduction events.

Activation of calcium/calmodulin-dependent kinase II following bovine rotavirus enterotoxin NSP4 expression
Objective(s): The rotavirus nonstructural protein 4 (NSP4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase C-dependent and phospholipase C-independent pathways in infected cells. It is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...

Molecular structure of a gene, ZmSTPK1, encoding a serine/threonine protein kinase in maize was analyzed by bioinformatic tool and its expression pattern was studied under chemical biological fertilizers. Bioinformatic analysis cleared that ZmSTPK1 is located on chromosome 10, from position 141015332 to 141017582. The full genomic sequence of the gene is 2251 bp in length and includes 2 exons. ...

Long-term potentiation (LTP) is a form of activity dependent plasticity that induced by high-frequency stimulation or theta burst stimulation and results in synaptic transmission. Several Studies have been shown that LTP is one of the most important processes in the CNS that plays an important role in learning and memory formation. Ca2+/calmodulin-dependent protein kinase II (CaMKII) is a major...

A chimeric Ca2+/calmodulin-dependent protein kinase (CCaMK) gene characterized by a catalytic domain, a calmodulin-binding domain, and a neural visinin-like Ca2+-binding domain was recently cloned from plants (Patil, S., Takezawa, D., and Poovaiah, B. W. (1995) Proc. Natl. Acad. Sci. U. S. A. 92, 4797-4801). The Escherichia coli-expressed CCaMK phosphorylates various protein and peptide substra...
