title: The TGGCA-binding protein: a eukaryotic nuclear protein recognizing a symmetrical sequence on double-stranded linear DNA.
abstract: Low salt extracts of chicken oviduct nuclei contain a DNA binding protein with high affinity for specific DNA sequences in the flanking regions of the chicken lysozyme gene. Two of the three binding sites found within a total of 11 kb upstream from the promoter are located only 92 bp apart from each other. Upon comparison of the DNA binding sites, the symmetrical consensus sequence 5'- TGGCANNNTGCCA -3' can be deduced as the protein recognition site. This sequence is the central part of 23 to 25 base pairs protected by the DNA binding protein from DNAase I digestion. A homologous binding activity can be detected in nuclei from several chicken tissues and from mouse liver.
