Target Information

Steroid receptors are ligand-dependent intracellular proteins that stimulate transcription of specific genes by binding to specific DNA sequences following activation by the appropriate hormone. Prior to activation, steroid receptors associate with a number of different proteins in both a stable and transient fashion. Steroid receptor complex proteins include heat shock proteins (HSP70 and HSP90), immunosuppressant binding proteins (FKBP52 & FKBP54, CyP-40), and other proteins termed p23, p60, and p48.

p23, along with HSP70, HSP90, and p60, combine with the progesterone receptor (PR) as members of a transient intermediate complex. Cloned human p23 encodes a 160-amino-acid protein that is highly conserved between species and shows no homology to previously identified proteins. p23 is a highly acidic phosphoprotein with an aspartic acid-rich C-terminal domain and multiple potential phosphorylation sites. In vitro studies suggest that p23 binds to HSP90 and is necessary for the binding of HSP90 and CyP-40 to PR. While its exact function remains unclear, p23 appears to be an important factor in PR function.
