Identifying CpG islands on a promoter... - (May/27/2014 )

Trying to determine if CpG islands exist in a promoter I'm working with. CpG islands have been reported/published in the human genome for this gene (mitochondrial transcription factor A, to be specific), but I'm working with the proximal rat (rattus norvegicus) promoter for my work. How would I go about determining if CpG islands exist in my promoter?

Cheers!
