REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.

Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

This product is subject to limited use licenses from The Broad Institute, ERS Genomics Limited and Sigma-Aldrich Co. LLC, and is developed with patented technology. For full details of the licenses and patents please refer to our limited use license and patent pages.

Supplementary information

7-dehydrocholesterol reductase (DHCR7) is an enzyme that plays an important role in cholesterol biosynthesis. It catalyzes the conversion of 7-dehydrocholesterol (7-DHC) to cholesterol in the final step of the process. DHCR7 is also known by the name sterol Δ7-reductase. The enzyme has a molecular mass of approximately 54 kDa. Expression of DHCR7 is prominent in tissues that require active cholesterol synthesis such as the liver adrenal glands and brain.
Biological function summary

DHCR7 activity ensures the maintenance of cholesterol homeostasis in cells. The enzyme operates independently and does not form part of a larger complex focusing directly on the reduction of the double bond in the C7-8 position of 7-DHC to yield cholesterol. By regulating cholesterol levels DHCR7 supports membrane fluidity and integrity contributing to the proper function of cellular structures.

Pathways

DHCR7 is an important component of the cholesterol biosynthesis pathway which is part of the larger sterol metabolic pathway. Its function is linked with other enzymes such as 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) highlighting their roles in sequential steps that convert squalene into cholesterol. These interactions highlight the interdependence of DHCR7 with other sterol-processing proteins influencing both cholesterol production and regulation within the body.

DHCR7 mutations can cause conditions such as Smith-Lemli-Opitz syndrome a congenital disorder characterized by multiple physical and developmental abnormalities. This condition connects DHCR7 to defective cholesterol metabolism and accumulation of toxic 7-DHC levels. Additionally the involvement of DHCR7 in cholesterol homeostasis ties it with potential dyslipidemias where abnormal lipid levels may influence cardiovascular health. Changes in DHCR7 function can lead to disruptions in normal cholesterol synthesis impacting related proteins and enzymatic pathways.
