Characterization of a novel plant PP2C-like protein Ser/Thr phosphatase as a calmodulin-binding protein.
Protein phosphatases regulated by calmodulin (CaM) mediate the action of intracellular Ca2+ and modulate functions of various target proteins by dephosphorylation. In plants, however, the role of Ca2+ in the regulation of protein dephosphorylation is not well understood due to a lack of information on characteristics of CaM-regulated protein phosphatases. Screening of a cDNA library of the moss...
متن کاملMolecular characterization of calmodulin trapping by calcium/calmodulin-dependent protein kinase II.
Autophosphorylation of alpha-Ca(2+)/calmodulin-dependent protein kinase II (CaM kinase II) at Thr(286) results in calmodulin (CaM) trapping, a >10,000-fold decrease in the dissociation rate of CaM from the enzyme. Here we present the first site-directed mutagenesis study on the dissociation of the high affinity complex between CaM and full-length CaM kinase II. We measured dissociation kinetics...
متن کاملMolecular Characterization of a Three-disulfide Bridges Beta-like Neurotoxin from Androctonus crassicauda Scorpion Venom
Scorpion venom is the richest source of peptide toxins with high levels of specific interactions with different ion-channel membrane proteins. The present study involved the amplification and sequencing of a 310-bp cDNA fragment encoding a beta-like neurotoxin active on sodium ion-channel from the venom glands of scorpion Androctonus crassicauda belonging to the Buthidae family using r...

متن کاملIdentification and characterization of a Dictyostelium discoideum ribosomal protein gene.
We have identified a developmentally repressed large-subunit ribosomal protein gene of Dictyostelium discoideum based on sequence similarity to other ribosomal proteins. Protein rpl7 is homologous to large subunit ribosomal proteins from the rat and possibly to Mycoplasma capricolum and Escherichia coli, but is not similar to three sequenced ribosomal proteins in Dictyostelium. The rpl7 gene is...
