CC -!- FUNCTION: mRNA-binding protein involved in translation elongation. Has
CC an important function at the level of mRNA turnover, probably acting
CC downstream of decapping. Critical for the efficient synthesis of
CC peptide bonds between consecutive proline residues. Can resolve
CC ribosomal stalling caused by consecutive prolines during translation
CC (By similarity). Involved in actin dynamics and cell cycle progression,
CC mRNA decay and probably in a pathway involved in stress response and
CC maintenance of cell wall integrity. Functions as a regulator of
CC apoptosis. Mediates effects of polyamines on neuronal process extension
CC and survival. May play an important role in brain development and
CC function, and in skeletal muscle stem cell differentiation (By
CC similarity). {ECO:0000250, ECO:0000250|UniProtKB:P63241,
CC ECO:0000269|PubMed:14622290}.

CC Endoplasmic reticulum membrane {ECO:0000250}; Peripheral membrane
CC protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Nucleus, nuclear
CC pore complex {ECO:0000250}. Note=Hypusine modification promotes the
CC nuclear export and cytoplasmic localization and there was a dynamic
CC shift in the localization from predominantly cytoplasmic to primarily
CC nuclear under apoptotic inducing conditions. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in ovarian and colorectal cancer cell
CC lines (at protein level). Highly expressed in testis. Overexpressed in
CC some cancer cells. {ECO:0000269|PubMed:11161802,
CC ECO:0000269|PubMed:16519677}.
CC -!- PTM: Lys-50 undergoes hypusination, a unique post-translational
CC modification that consists in the addition of a butylamino group from
CC spermidine to lysine side chain and leads to the formation of a
CC hypusine residue. eIF-5As are the only known proteins to undergo this
CC modification, which is essential for their function.
CC {ECO:0000269|PubMed:14622290}.
CC -!- SIMILARITY: Belongs to the eIF-5A family. {ECO:0000305}.
