A fusicoccin binding protein belongs to the family of 14-3-3 brain protein homologs.
The fusicoccin binding protein (FCBP) is a highly conserved plasma membrane protein present in all higher plants tested thus far. It exhibits high- and low-affinity binding for the fungal toxin fusicoccin (FC). We purified the active FCBP from a fraction highly enriched in plasma membrane by selective precipitation and anion exchange chromatography. After SDS-PAGE, the two FCBP subunits of 30 a...
متن کاملThe 30-kilodalton protein present in purified fusicoccin receptor preparations is a 14-3-3-like protein.
We have recently reported on the purification of the fusicoccin (FC) receptor from corn (Zea mays L.) and its identification by photoaffinity labeling (P. Aducci, A. Ballio, V. Fogliano, M.R. Fullone, M. Marra, N. Proietti [1993] Eur J Biochem 214: 339-345). Pure preparations of FC receptors, obtained under nondenaturing conditions, showed in sodium dodecyl sulfate-polyacrylamide gel electropho...
متن کاملStructural basis for protein-protein interactions in the 14-3-3 protein family.
The seven members of the human 14-3-3 protein family regulate a diverse range of cell signaling pathways by formation of protein-protein complexes with signaling proteins that contain phosphorylated Ser/Thr residues within specific sequence motifs. Previously, crystal structures of three 14-3-3 isoforms (zeta, sigma, and tau) have been reported, with structural data for two isoforms deposited i...
متن کاملA plant homologue to mammalian brain 14-3-3 protein and protein kinase C inhibitor.
We have isolated cDNA clones of Spinacea oleracea L. and Oenothera hookeri of 930 and 1017 base pairs, respectively. The open reading frame deduced from the Oenothera sequence codes for a protein of a calculated molecular mass of 29,200. The primary amino acid sequence exhibits a very high degree (88%) of homology to the 14-3-3 protein from bovine brain, and protein kinase C inhibitor from shee...
متن کاملA calcium and free fatty acid-modulated protein kinase as putative effector of the fusicoccin 14-3-3 receptor.
A protein kinase that is activated by calcium and cis-unsaturated fatty acids has been characterized from oat (Avena sativa L.) root plasma membranes. The kinase phosphorylates a synthetic peptide with a motif (-R-T-L-S-) that can be phosphorylated by both protein kinase C (PKC) and calcium-dependent protein kinase (CDPK)-type kinases. Calphostin C and chelerythrine, two PKC inhibitors, complet...
