Androgens exert their effects by binding to the highly specific androgen receptor (AR). In addition to natural potent androgens, AR binds a variety of synthetic agonist or antagonist molecules with different affinities. To identify molecular determinants responsible for this selectivity, we have determined the crystal structure of the human androgen(More)
The aldo-keto reductase (AKR) human type 3 3alpha-hydroxysteroid dehydrogenase (h3alpha-HSD3, AKR1C2) plays a crucial role in the regulation of the intracellular concentrations of testosterone and 5alpha-dihydrotestosterone (5alpha-DHT), two steroids directly linked to the etiology and the progression of many prostate diseases and cancer. This enzyme also(More)
Fusion proteins integrating dual pesticidal functions have been devised over the last 10 years to improve the effectiveness and potential durability of pest-resistant transgenic crops, but little attention has been paid to the impact of the fusion partners on the actual activity of the resulting hybrids. Here we assessed the ability of the rice cysteine(More)
