If the gene isn't expressed, you should find stop codons in the coding
region. Perhaps try a tblastn search (blast) of the nr database.

Alignments using the protein or the DNA?

Perhaps finding a concensus sequence for the multiple set and the query on
the other. Dottup and Dotter programs work well.
