Anti-WDR85 antibodies enable researchers to detect and measure the WDR85 antigen in biological samples. This target is a reported synonym of the DPH7 gene, which encodes diphthamide biosynthesis 7. This protein is known to catalyze the demethylation of diphthine methyl ester to form diphthine, an intermediate diphthamide biosynthesis, a post-translational modification of histidine which occurs in translation elongation factor 2 (EEF2) which can be ADP-ribosylated by diphtheria toxin and by Pseudomonas exotoxin A (Eta). The human version of WDR85 has a canonical amino acid length of 452 residues and a protein mass of 50.6 kilodaltons. WDR85 is a member of the DPH7 protein family.
