Calmodulin and calmodulin-binding proteins in brain.
filament preparations isolated from many different species. Incubation of crude and purified preparations of filaments with [f2P]ATP labels nearly all the filament proteins (Fig. l), the exception being the 65000-mol.wt. band of Loligo (Fig. la). Phosphorylation in vitro is mediated by a cyclic AMPand Ca2+-independent, and Mg2+-dependent, protein kinase. The enzyme is activated by Na+ and K+ an...
متن کاملCalmodulin and Calmodulin-binding Proteins in Plants.
Calmodulin is a small Ca2+-binding protein that acts to transduce second messenger signals into a wide array of cellular responses. Plant calmodulins share many structural and functional features with their homologs from animals and yeast, but the expression of multiple protein isoforms appears to be a distinctive feature of higher plants. Calmodulin acts by binding to short peptide sequences w...
متن کاملIdentification and characterization of the calmodulin-binding domain of neuromodulin, a neurospecific calmodulin-binding protein.
Neuromodulin (formerly designated P-57) is an abundant, neural specific, calmodulin-binding protein which exhibits higher affinity for calmodulin in the absence of free Ca2+ than in the presence of free Ca2+. In this study a series of proteolytic fragments of neuromodulin were systematically screened for calmodulin-Sepharose binding activity. A 9-amino acid fragment, designated M1-C1 and having...
متن کاملIdentification of Calmodulin-binding Proteins in Chicken Embryo Fibroblasts
We recently reported the detection of multiple classes of calmodulin-binding proteins in subcellular fractions of chicken embryo fibroblasts by using a gel binding procedure (Van Eldik, L . J ., and W. H . Burgess, 1983, J . Biol. Chem ., 258:4539-4547) . In this report we identify many of these calmodulin-binding proteins and provide further evidence for the existence of multiple classes of ca...
