I find Entrez <http://atlas.nlm.nih.gov:5700/Entrez/index.html> to be the
best tool for tracking down sequences.  However, I didn't find any
non-yeast STE2 or STE3 sequences in the GenBank database that Entrez uses,
nor any relevant epithelial sequences from authors named Patel.   Since I
don't have access to the article you cited, I wasn't able to figure out if
the authors published the sequences of the human STE2 and STE3 genes.  If
they did, it would be easy to compare them against the yeast STE2 and STE3
genes.  If they didn't publish any sequence, I'm not sure you will find
any other publicly available databases that might answer whether the human
and yeast genes are related. 

Hope this helps.
