Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Stearoyl-CoA desaturase that utilizes O(2) and electrons from reduced cytochrome b5 to introduce the first double bond into saturated fatty acyl-CoA substrates. Catalyzes the insertion of a cis double bond at the delta-9 position into fatty acyl-CoA substrates including palmitoyl-CoA and stearoyl-CoA (PubMed:12815040, PubMed:16443825). Required for the biosynthesis of membrane phospholipids, cholesterol esters and triglycerides (By similarity).CATALYTIC ACTIVITY octadecanoyl-CoA + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = (9Z)-octadecenoyl-CoA + 2 Fe(III)-[cytochrome b5] + 2 H2OCATALYTIC ACTIVITY hexadecanoyl-CoA + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = (9Z)-hexadecenoyl-CoA + 2 Fe(III)-[cytochrome b5] + 2 H2OCOFACTOR Expected to bind 2 Fe(2+) ions per subunit.SUBCELLULAR LOCATION Detected in heart, but not in brain, liver, skin or adipose tissue.INDUCTION Up-regulated by agonists that activate NR1H3. Up-regulated by a fat-free high-carbohydrate diet. Not down-regulated by a high-carbohydrate diet supplemented with unsaturated fatty acids. Down-regulated by leptin.DOMAIN The histidine box domains are involved in binding the catalytic metal ions.SIMILARITY Belongs to the fatty acid desaturase type 1 family.
