Expressed sequence tags identify a human isolog of the suil translation initiation factor

The complete cDNA sequence of a human isolog of the yeast suil translation initiation factor gene was obtained by assembling over 40 expressed sequence tags (ESTs) for this gene obtained from a variety of tissue-specific cDNA libraries. The human suilisol gene product is a 113 amino-acid polypeptide similar to proteins known from yeast, rice, mosquito, and Methanococcus. The identification of suilisol illustrates the utility of assemblies of independent ESTs for deriving full-length cDNA sequences for new human genes.
