DPH1 homolog
OVCA1, Dph1, DPH2L, DPH2L1
Diphthamide is a unique posttranslationally modified histidine found only in translation elongation factor-2 (EEF2; MIM 130610). This modification is conserved from archaebacteria to humans and serves as the target for ADP-ribosylation and inactivation of EEF2 by diphtheria toxin (DT) and Pseudomonas exotoxin A. DPH1 is 1 of several enzymes involved in synthesis of diphthamide in EEF2 (Liu et al., 2004 [PubMed 15485916]).[supplied by OMIM, Mar 2008] (from
NCBI)

Review
Leicester, United Kingdom. In Mol Microbiol, 2014
However, recent progress in dissecting the diphthamide gene network (DPH1-DPH7) from the budding yeast Saccharomyces cerevisiae has significantly advanced our understanding of the mechanisms required to initiate and complete diphthamide synthesis on EF2.

Bethesda, United States. In Leuk Res, 2013
To understand how to increase response rate, we isolated HA22-resistant KOPN-8 cells and found that HA22 cannot inactivate elongation factor-2 (EF2) due to low levels of DPH1 RNA and protein.
