DFRP_C is a family of eukaryotic translation machinery-associated protein 46 proteins that are the binding partner for the highly conserved Developmentally Regulated GTP-binding (DRG) GTPases. Thus this family is referred to as DRG Family Regulatory Proteins (DFRP). Binding of this DFRP modulates the function of the GTPase [1].
