A new family of transcription factors.
CudA, a nuclear protein required for Dictyostelium prespore-specific gene expression, binds in vivo to the promoter of the cotC prespore gene. A 14 nucleotide region of the cotC promoter binds CudA in vitro and ECudA, an Entamoeba CudA homologue, also binds to this site. The CudA and ECudA DNA-binding sites contain a dyad and, consistent with a symmetrical binding site, CudA forms a homodimer i...
متن کاملMarR family transcription factors
Figure 1. Representative MarR homologs and their mode of gene regulation. (A) Structure of MTH313 (3BPX), a MarR homolog of unknown function from Methanobacterium thermoautotrophicum, in complex with the ligand salicylate (shown in magenta). One monomer is shown in gray, the other is colored from amino to carboxyl terminus (blue to red). Note the asymmetrical ligand binding; only ligand binding...
متن کاملImpacts of a new transcription factor family
GCM proteins constitute a small transcription factor family with a DNA-binding domain exhibiting a novel fold composed of two subdomains rigidly held together by coordination of one of two structural zinc cations. In all known cases, GCM proteins exert the role of master regulators: the prototypical family member determines gliogenesis in Drosophila melanogaster, whereas mammalian GCM proteins ...
متن کاملA novel DNA-binding motif, hallmark of a new family of plant transcription factors.
A novel family of plant-specific transcription factors is described. They are structurally related to DBP1 (for DNA-binding protein phosphatase 1), a new transcription factor recently characterized in tobacco (Nicotiana tabacum), which exhibits both sequencespecific DNA-binding and protein phosphatase activity (Carrasco et al., 2003). The C-terminal part of DBP factors shows high sequence simil...
متن کاملThe Sp-family of transcription factors.
GC-boxes and related motifs are frequently occurring DNA-elements present in many promoters and enhancers. In contrast to other elements it was generally thought that the transcription factor Sp1 is the only factor acting through these motifs. The cloning of paralogous genes of the Sp1 factor uncovered the existence of a small protein family consisting of Sp1, Sp2, Sp3 and Sp4. All four protein...
