Eukaryotic translation initiation factor 5A-1 is a protein that in humans is encoded by the EIF5A gene.

It is the only known protein to contain the unusual amino acid hypusine , which is synthesized on eIF5A at a specific lysine residue from the polyamine spermidine by two catalytic steps.

EF-P is the bacterial homolog of eIF5A, which is modified post-translationally in a similar but distinct way. Both proteins are believed to catalyze peptide bond formation and help resolve ribosomal stalls, making them elongation factors despite the "initiation factor" name originally assigned.

Faundes-Banka syndrome

Germline deleterious heterozygous EIF5A variants cause Faundes-Banka syndrome. This rare human disorder is characterized by variable combinations of developmental delay, microcephaly, micrognathia and dysmorphic features. It was named after Víctor Faundes and Siddharth Banka.
