Evidence for a negative feedback control mediated by the 3′ untranslated region assuring the low expression level of the RNA binding protein TcRBP19 in T. cruzi epimastigotes

- tcrbp19 3′UTR affects the level of reporter mRNA along T. cruzi life cycle.
- The TcRBP19 binding to its own transcript was demonstrated.
- TcRBP19 over-expression reduces endogenous tcrbp19 mRNA stability in epimastigotes.
