A novel Arabidopsis DNA binding protein contains the conserved motif of HMG-box proteins.
We have isolated cDNA clones from a lambda gtll library of mRNA prepared from rosette plants of Arabidopsis thaUana to identify DNA binding proteins that bind to the promoter region of the desiccation-responsive rd29A gene (1, 2, 3). We used a 40 bp conserved sequence (3) in the promoter regions of rd29A and rd29B genes, which may contain enhancer-like sequence(s), as a probe for the screening....
متن کاملCharacterization of the Arabidopsis Adh G-box binding factor.
Protein-DNA interaction at an inverted repeat of the sequence 5'-GTGG-3' (G-box) has been associated with the transcription of several plant genes [Giuliano, G., et al. (1988). Proc. Natl. Acad. Sci. USA 85, 7089-7093; Ferl, R.J., and Laughner, B.H. (1989). Plant Mol. Biol. 12, 357-366; Schulze-Lefert, P., et al. (1989). EMBO J. 8, 651-656]. We characterized the binding of the Arabidopsis G-box...
متن کاملMolecular dissection of GT-1 from Arabidopsis.
We isolated and characterized an Arabidopsis cDNA encoding the DNA binding protein GT-1. This protein factor, which contains 406 amino acids, is highly homologous to the previously described tobacco DNA binding protein GT-1a/B2F but is 26 amino acids longer. Recombinant Arabidopsis GT-1, which was obtained from in vitro translation, bound to probes consisting of four copies of pea small subunit...
متن کاملProximal promoter of the surfactant protein D gene: regulatory roles of AP-1, forkhead box, and GT box binding proteins.
Surfactant protein D (SP-D) plays roles in pulmonary host defense and surfactant homeostasis and is increased following lung injury. Because AP-1 proteins regulate cellular responses to diverse environmental stimuli, we hypothesized that the conserved AP-1 motif (at -109) and flanking sequences in the human SP-D promoter contribute to the regulation of SP-D expression. The AP-1 sequence specifi...
متن کاملFunctional analysis of glycin rich- RNA binding protein, a suppressor of trehalose-6-phosphate mediating growth arrest in Arabidopsis thaliana
Metabolism of the alpha-1,1 glucose disaccharide, trehalose, is indispensable in plants. In the Murashigeand Skoog (MS) medium, trehalose inhibits plant growth and allocation of carbon to roots. A suppressorof trehalose-6-phosphate (T6P) mediated growth arrest, GR-RBP2, is characterized in more detail.Phylogenetic analysis revealed that GR-RBP2 is a protein of likely prokaryot...
