Overlay histogram showing Jurkat cells stained with ab32407 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab32407, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monclonal) (1μg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Supplementary information

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.

Target data

Translation factor that promotes translation elongation and termination, particularly upon ribosome stalling at specific amino acid sequence contexts (PubMed : 33547280). Binds between the exit (E) and peptidyl (P) site of the ribosome and promotes rescue of stalled ribosome : specifically required for efficient translation of polyproline-containing peptides as well as other motifs that stall the ribosome (By similarity). Acts as a ribosome quality control (RQC) cofactor by joining the RQC complex to facilitate peptidyl transfer during CAT tailing step (By similarity). 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 (PubMed : 16987817). With syntenin SDCBP, functions as a regulator of p53/TP53 and p53/TP53-dependent apoptosis (PubMed : 15371445). Regulates also TNF-alpha-mediated apoptosis (PubMed : 15452064, PubMed : 17187778). Mediates effects of polyamines on neuronal process extension and survival (PubMed : 17360499). Is required for autophagy by assisting the ribosome in translating the ATG3 protein at a specific amino acid sequence, the 'ASP-ASP-Gly' motif, leading to the increase of the efficiency of ATG3 translation and facilitation of LC3B lipidation and autophagosome formation (PubMed : 29712776).. (Microbial infection) Cellular cofactor of human T-cell leukemia virus type I (HTLV-1) Rex protein and of human immunodeficiency virus type 1 (HIV-1) Rev protein, essential for mRNA export of retroviral transcripts.
