Purine Rich Region in Promoter

[DAVID MITCHELL]

Dear Netters,

I have a fungal gene that contains a purine (thats A's and G's folks) rich
region upstream of the translated region.  It's probably just before the
transcription start site(s) but I have not mapped them for sure.  There is
certainly a lot of literature about pyrimidine (CT) rich regions in yeast and
fungal promotors but I can't find any reference to purine rich rigions.  

The Question:  Has anybody heard of such a region before, anywhere?

Many thanks and have a nice weekend.
