The unusual amino acid hypusine is formed
posttranslationally and is only found in a single cellular protein,
eukaryotic translation initiation factor 5A. In the first step of
hypusine biosynthesis, deoxyhypusine synthase catalyzes the
NAD-dependent transfer of the butylamine moiety of spermidine to
the epsilon-amino group of a specific lysine residue of the EIF5A
precursor protein to form the intermediate deoxyhypusine residue.
This gene consists of nine exons spanning 6.6 kb. Three transcript
variants have been isolated. However, only transcript variant 1
encodes an active protein. The shorter variants may act as
modulating factors of DHPS activity.1) Venkatesan, K., et al. Nat. Methods 6(1):83-90(2009)
Immunogen
This DHPS antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 16-43 amino acids from the N-terminal region of human DHPS.
Western blot analysis in Jurkat cell line lysates (35ug/lane).
