title: A proposed consensus steroid-binding sequence--a reply.
abstract: A consensus sequence has been proposed as necessary for steroid binding on the basis of sequence homology in steroidogenic enzymes, steroid binding proteins and steroid receptors. We have mapped the limit of sequences important for steroid binding in the mouse estrogen receptor using Scatchard analysis of deletion mutants. Since a mutant lacking the entire proposed consensus is still able to bind estradiol with essentially wild type affinity, the functional significance of this motif is unclear.
