DNA binding and dimerisation determinants of Antirrhinum majus MADS-box transcription factors.
Members of the MADS-box family of transcription factors are found in eukaryotes ranging from yeast to humans. In plants, MADS-box proteins regulate several developmental processes including flower, fruit and root development. We have investigated the DNA-binding mechanisms used by four such proteins in Antirrhinum majus, SQUA, PLE, DEF and GLO. SQUA differs from the characterised mammalian and ...
متن کاملGenomic regions flanking E-box binding sites influence DNA binding specificity of bHLH transcription factors through DNA shape.
DNA sequence is a major determinant of the binding specificity of transcription factors (TFs) for their genomic targets. However, eukaryotic cells often express, at the same time, TFs with highly similar DNA binding motifs but distinct in vivo targets. Currently, it is not well understood how TFs with seemingly identical DNA motifs achieve unique specificities in vivo. Here, we used custom prot...
متن کاملComprehensive interaction map of the Arabidopsis MADS Box transcription factors.
Interactions between proteins are essential for their functioning and the biological processes they control. The elucidation of interaction maps based on yeast studies is a first step toward the understanding of molecular networks and provides a framework of proteins that possess the capacity and specificity to interact. Here, we present a comprehensive plant protein-protein interactome map of ...
متن کاملDeterminants of the DNA binding specificity of class I and class II TCP transcription factors.
TCP proteins constitute a family of plant transcription factors with more than 20 members in angiosperms. They can be divided in two classes based on sequence homology and the presence of an insertion within the basic region of the TCP DNA binding and dimerization domain. Here, we describe binding site selection studies with the class I protein TCP16, showing that its DNA binding preferences ar...
متن کاملDNA-binding specificity of GATA family transcription factors.
GATA-binding proteins constitute a family of transcription factors that recognize a target site conforming to the consensus WGATAR (W = A or T and R = A or G). Here we have used the method of polymerase chain reaction-mediated random site selection to assess in an unbiased manner the DNA-binding specificity of GATA proteins. Contrary to our expectations, we show that GATA proteins bind a variet...
