EIF5A also known as eukaryotic translation initiation factor 5A is a small protein with a molecular mass of approximately 18 kDa. It plays a significant mechanical role in the translation process by facilitating the formation of the first peptide bond in protein synthesis. eIF5A is expressed ubiquitously across various tissues and is noted for being the only protein known to undergo the unique post-translational modification called hypusination which is necessary for its function.
Biological function summary
EIF5A participates in regulating translation cell proliferation and apoptosis. eIF5A functions as part of a complex involved in ribosome-associated protein synthesis supporting the elongation of polyproline-containing peptides. It helps in maintaining cellular homeostasis by modulating the translation of specific sets of mRNAs that are critical for various cellular responses.
Pathways
EIF5A's role is particularly relevant in translation elongation and mRNA turnover pathways. It interacts closely with the elongation factors eEF2 and eEF1A to promote efficient protein synthesis. In the mRNA turnover pathway eIF5A has connections with proteins such as Dcp2 and Xrn1 which play a role in the degradation of mRNA thereby influencing mRNA stability and turnover.
EIF5A is linked to cancer and neurodegenerative diseases. Alterations in its function and expression levels have been observed in several cancer types highlighting its role in tumor progression. The protein's connection to apoptosis pathways suggests its involvement in neurodegenerative disorders such as Alzheimer's disease where cell death and tissue degeneration are prevalent. eIF5A associates with proteins like Bcl-2 in cancer and Tau in neurodegeneration indicating its varied impact on disease processes.
