There are several ways in which you can perform such an analysis.
While there are several different email servers which will 
search for possible regulatory regions in a queried sequence, 
you may find it easier (and more applicable to the situation 
that you detailed), to first analyze your sequences for regions 
of similarity.  There are several software programs that will search for 
similarities in different sequences, depending upon the type of platform 
you're utilizing (i.e. Unix / DOS / etc.).  Upon determining these 
regions(s) in your sequences, you can utilize a "consensus" sequence as 
a query for the previously mentioned email server search.

Feel free to contact me if you have any further questions:
