YY1 binding sites in genomic context. YY1 binding sites are mapped onto the Custom Track of the UCSC Genome Browser http://genome.ucsc.edu/. YY1 binding sites are marked by blue and red bars indicating forward and reverse directions respectively. Height on the Y-axis represents the score of each YY1 binding site in relation to the consensus sequence. This 100 kb segment of the genome contains five olfactory receptor genes and shows association of several YY1 binding sites correlated with the exons of the genes. Mammalian conservation is shown in the plot at the bottom of the map. This map was created through scanning the RepeatMasked sequence with a scoring matrix representing the YY1 binding site consensus. Mammalian conservation correlates with exons as expected, but also with many YY1 binding sites in this region.
