Figure 1. 5′-Flanking sequence of bovine PLCz from −461 bp to +100 bp.

This fragment contains the promoter exon 1 and a part of intron 1. Boxed sequences represent the putative transcription factor binding sites. The nucleotides highlighted in red represent the two polymorphic sites in Chinese Holstein bulls. The nucleotide sequence numbered +1 is A of the TSS. The numbering of nucleotides is relative to the transcription start site.
