Yes, maintained at several sites, I grabbed the one below at the Indiana
Gopher site, gopher://ftp.bio.indiana.edu/
BTW, you should make your subject line more informative. For example,
"need Rat codons."

Rattus sp. (Rat)
833 genes found in GenBank 63.
Produced by J. Michael Cherry (cherry at frodo.mgh.harvard.edu) with the
GCG program CodonFrequency.
Duplicates, pseudogenes, mutant and synthetic genes were not included.
Coding regions were specified using the Feature Table of each entry, then
checked for accuracy. If more than one stop codon was found the sequence
was not included.
