Abstract

The 3' untranslated regions of a number of cDNAs from the rumen protozoal species Entodinium caudatum were studied with a view to characterising their preference for stop codons, general length, nucleotide composition and polyadenylation signals. Unlike a number of ciliates, Entodinium caudatum uses UAA as a stop codon, rather than as a codon for glutamine. In addition, the 3' untranslated region of the message is generally less than 100 nucleotides in length, extremely A+T rich, and does not appear to utilise any of the conventional polyadenylation signals described in other organisms.
