The identification of such ligands for therapeutically relevant but "undruggable" proteins remains challenging. Herein, we employed yeast surface display of synthetic nanobodies to identify a protein ligand selective for BCL11A, a critical repressor of fetal globin gene transcription. Fusion of the nanobody to a cell-permeant miniature protein and an E3 adaptor creates a degrader that depletes cellular BCL11A in differentiated primary erythroid precursor cells, thereby inducing the expression of fetal hemoglobin, a modifier of clinical severity of sickle cell disease and beta-thalassemia. Our strategy provides a means of fetal hemoglobin induction through reversible, temporal modulation of BCL11A. Additionally, it establishes a new paradigm for the targeted degradation of previously intractable proteins.
