The NANOG interaction domain 2 of TET1 binds NANOG using phenylalanine residues. (a) and (b) Co-immunoprecipitation of the (Flag)3-TET1 constructs (a) with (HA)3-NANOG from E14/T ESCs. (b) Immunoblots were probed with the antibodies indicated on the left (representative images, n = 3). (c) and (d) Co-immunoprecipitation of alanine substitution mutants of (Flag)3-TET1(734–1169) with (HA)3-NANOG from E14/T ESCs. (c) Alanine substitutions of the amino acids within residues 1156–1169. (d) Immunoblots were probed with the antibodies indicated on the left (representative images, n = 2).
