Using an oligodeoxynucleotide generated by rapid PCR amplification of
5'-cDNA ends (5'-RACE) as a detection probe, we have isolated a new ge
nomic clone encoding the human eukaryotic initiation factor 5A (eIF-5A
), Sequence analysis revealed that the eIF-5A coding region is identic
al to the corresponding cDNA but interrupted by three introns, In a pl
asmid shuffle experiment we show functional replacement of the essenti
al homologous gene in Saccharomyces cerevisiae by this human eIF-5A.
