Background Information

Eukaryotic initiation factor 5A (EIF5A) plays an essential role in the viability of eukaryotic cells. EIF5A is known to act as a translation initiation factor specific for a small number of mRNAs, a cellular target of HIV-1 REV protein, and an exportin-4-dependent nuclear export cargo. It is also involved in mRNA turnover and the establishment of actin polarity. [PMID:16157662]. EIF5A2, one isoform of EIF5A, has a key at the level of mRNA turnoverby acting downstream of decapping. It also involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity [PMID:14622290]. EIF5A2 shares 84% identity of amino acid sequence with EIF5A1 isoform, so EIF5A2 poly-antibody could recognize both EIF5A2 and EIF5A1.
