背景
function:The precise role of eIF-5A in protein biosynthesis is not known but it functions by promoting the formation of the first peptide bond.,PTM:eIF-5A seems to be the only eukaryotic protein to have an hypusine residue which is a post-translational modification of a lysine by the addition of a butylamino group (from spermidine).,similarity:Belongs to the eIF-5A family.,subunit:Found in a complex with Ran and XPO4. The hypusine modification increases the interaction with XPO4.,tissue specificity:Expressed in umbilical vein endothelial cells and several cancer cell lines (at protein level).,
