The protein and DNA constructs used in characterization and crystallization. (a) Human HNF4α-DBD protein sequence. The predicted DNA-recognition helix is boxed and the MODY mutations are shown in red. Cloning artifacts from the expression vector are indicated by lower case letters at the N-terminal end. (b) The natural HNF1α promoter sequence (−46 to −66; Gragnoli et al., 1997) containing the HNF4α recognition site used in crystallization and binding studies. Two direct-repeat half-sites are boxed and the MODY mutation is shown in red. |
