  sub:_5 prov:value "The LHbeta promoter is regulated by the orphan nuclear receptor SF-1 and homeodomain protein Ptx1. Although each factor enhances the LHbeta promoter, coexpression of both results in a strong synergistic activation. Therefore, we examined whether MIP-2A can modulate SF-1- and Ptx1-mediated transcriptional activation. Our results suggested that MIP-2A expression inhibits SF-1- and Ptx1-mediated transactivation of LHbeta promoter. Subsequent analysis demonstrated that MIP-2A physically interacts with both SF-1 and Ptx1, thereby inhibiting transactivation of the LHbeta promoter" ;
