The present invention relates to unique isoforms of eukaryotic initiation
Factor 5A ("eIF-5A"): senescence-induced eIF-5A; wounding-induced eIF-5A;
and growth eIF-5A, as well as polynucleotides that encode these three
factors. The present invention also relates to methods involving
modulating the expression of these factors. The present invention also
relates to deoxyhypusine synthase ("DHS"), polynucleotides that encode
DHS, and methods involving modulating the expression of DHS.
