Summaries for STS Gene

Entrez Gene Summary for STS Gene

  • The protein encoded by this gene catalyzes the conversion of sulfated steroid precursors to estrogens during pregnancy. The encoded protein is found in the endoplasmic reticulum, where it acts as a homodimer. Mutations in this gene are known to cause X-linked ichthyosis (XLI). [provided by RefSeq, Jul 2008]

GeneCards Summary for STS Gene

STS (Steroid Sulfatase (Microsomal), Isozyme S) is a Protein Coding gene. Diseases associated with STS include ichthyosis, x-linked and syndromic x-linked ichthyosis. Among its related pathways are PTM- gamma carboxylation, hypusine formation and arylsulfatase activation and PTM- gamma carboxylation, hypusine formation and arylsulfatase activation. GO annotations related to this gene include sulfuric ester hydrolase activity and steryl-sulfatase activity. An important paralog of this gene is ARSJ.
