We performed a comparative analysis of the effect of high-mobility group box protein 1 (HMGB1) on DNA binding by the DNA-binding domains (DBDs) of the androgen, glucocorticoid, progesterone and mineralocorticoid receptors. The affinity of the DBDs of the different receptors for the tyrosine aminotransferase glucocorticoid response element, a classical high-affinity binding element, was augmented up to 7-fold by HMGB1. We found no major differences in the effects of HMGB1 on DNA binding between the different steroid hormone receptors. In transient transfection assays, however, HMGB1 significantly enhances the activity of the glucocorticoid and progesterone receptors but not the androgen or mineralocorticoid receptor. We also investigated the effect of HMGB1 on the binding of the androgen receptor DBD to a subclass of directly repeated response elements that is recognized exclusively by the androgen receptor and not by the glucocorticoid, progesterone or mineralocorticoid receptor. Surprisingly, a deletion of 26 amino acid residues from the C-terminal extension of the androgen receptor DBD does not influence DNA binding but destroys its sensitivity to HMGB1. Deletion of the corresponding fragment in the DBDs of the glucocorticoid, progesterone and mineralocorticoid receptor destroyed their DNA binding. This 26-residue fragment is therefore essential for the influence of HMGB1 on DNA recognition by all steroid hormone receptors that were tested. However, it is dispensable for DNA binding by the androgen receptor.

Dimeric transcription factors that bind to DNA are often grouped into families on the basis of dimerization and DNA-binding specificities. cDNA cloning studies have established that members of the same family have structurally related dimerisation and DNA-binding domains but diverge in other regions that are important for transcriptional activation. These features lead to the straightforward suggestion that although all members of a family bind to similar DNA elements, individual members exhibit distinct transcriptional effector functions. This simple view is now supported by experimental evidence from those systems that have proved amenable to study. There are however some largely unaddressed questions that concern the mechanisms that allow family members to go about their business without interference from their highly related siblings. Here I will discuss some insights from studies of the bZIP class of transcription factors.
