External Ids for DPH5 Gene
This gene encodes a component of the diphthamide synthesis pathway. Diphthamide is a post-translationally modified histidine residue found only on translation elongation factor 2. It is conserved from archaebacteria to humans, and is targeted by diphtheria toxin and Pseudomonas exotoxin A to halt cellular protein synthesis. The yeast and Chinese hamster homologs of this protein catalyze the trimethylation of the histidine residue on elongation factor 2, resulting in a diphthine moiety that is subsequently amidated to yield diphthamide. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
GeneCards Summary for DPH5 Gene
DPH5 (Diphthamide Biosynthesis 5) is a Protein Coding gene. Among its related pathways are diphthamide biosynthesis. GO annotations related to this gene include diphthine synthase activity.
UniProtKB/Swiss-Prot for DPH5 Gene
S-adenosyl-L-methionine-dependent methyltransferase that catalyzes the trimethylation of the amino group of the modified target histidine residue in translation elongation factor 2 (EEF2), to form an intermediate called diphthine. The three successive methylation reactions represent the second step of diphthamide biosynthesis.
