UniProtKB - Q4GZD1 (DHYSP_TRYB2)
Protein
Deoxyhypusine synthase regulatory subunit
Gene
DHSp
Organism
Trypanosoma brucei brucei (strain 927/4 GUTat10.1)
Status
Functioni
Required for the activation and stability of deoxyhypusine synthase DHSc. Required for cell growth and survival.1 Publication
Caution
Lacks the conserved active site Lys, and therefore lacks catalytic activity.1 Publication
