Steroid sulfatase (STS) is a membrane-bound microsomal enzyme that hydrolyzes various alkyl and aryl steroid sulfates, leading to the in situ formation of biologically active hormones. The entire human STS gene spans over approximately 200kbp of which the first 100kbp include the regulatory region, while the STS-coding region is located downstream. Previous(More)
Organic anion transporting polypeptides (OATPs) are a group of transmembrane carriers with a wide spectrum of amphipathic substrates. In particular, OATP2B1 (previously called OATP-B) can transport steroid hormone conjugates and is expressed in organs with steroidogenic activity, such as placenta, brain and skin. In this work, we have analyzed the(More)
