We have demonstrated previously that two binding sites in the - 184 HNF - 3 beta promoter are recognized by widely distributed factors and that there is also a critical autoregulatory site , we identified a binding site for a cell - specific factor , LF - H3 beta , that may function in restricting HNF - 3 beta gene expression to hepatocytes .
 - 184 HNF - 3 beta promoter, LF - H3 beta, HNF - 3 beta gene
