Fig. 1.
Graphic representation of the ovine HSP90AA1 CpG island (based on the reference sequence from the NCBI database, DQ983231.1; 5917 bp). The X axis represents the base pairs, while the Y axis represents the percentage of GC (data obtained from the Sequence Manipulation Suite http://www.bioinformatics.org/sms/cpg_island.html). The putative CpG island spans through the core promoter including the heat shock element (HSE), TATA box, and initiator element, also the exon 1,intron 1, exon 2, and intron 2 (see top of the figure)
