Figure 3. Putative eIF5A regulon.
Hypusine-containing eIF5A is proposed to affect protein expression by enhancing the translation of Group 1 mRNAs (resulting in up-regulation), and the turnover of Group 2 mRNAs (resulting in down-regulation). The targets may be direct or secondary to eIF5A's biochemical action, are collectively considered the eIF5A regulon, and influence tumorigenesis and related cellular processes.
