expression of dirrefent isoforms f the same gene in different tissues - (Oct/26/2011 )

Hi,

I was wondering if anyone knows a database or any other resource where I coud find which isoform of a gene expressed in which tissue. For example, I am looking into OPRM1 gene which has 13 isoforms and I would like to know which ones are expressed in the brain and which are not. I've tried to look at GEO information in NCBI, but I am fraid I know too little to understand it. Any suggestions? Any idea/help would be greately appreciated!

Many thanks,
T

FastDB (http://www.fast-db.com/fastdb2/frame.html) sometimes has some information about tissue specificity.

Cheers,
Roel
