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

Squalene epoxidase also called squalene monooxygenase is an essential enzyme in cholesterol biosynthesis. It converts squalene into 23-oxidosqualene through an epoxidation reaction involving the addition of an oxygen atom into the squalene molecule. The enzyme has an estimated mass of about 64 kDa and is primarily expressed in the liver where cholesterol synthesis is highly active. Its activity leads to the production of sterol intermediates which are further processed to form cholesterol and other sterols.
Biological function summary

Squalene epoxidase plays an important role in maintaining sterol homeostasis by regulating the conversion of squalene an important precursor in the cholesterol synthesis pathway. This enzyme operates as a part of the endoplasmic reticulum membrane complex where it anchors and acts on substrates to produce sterol intermediates for further enzymatic actions. Its function is tightly regulated by intracellular cholesterol levels to prevent overproduction and maintain cell membrane integrity.

Pathways

Squalene epoxidase is an important component of the mevalonate pathway a fundamental route for the synthesis of cholesterol and other isoprenoids. Besides cholesterol biosynthesis it connects to the synthesis of steroid hormones and bile acids. Farnesyl pyrophosphate another key intermediate in the mevalonate pathway influences the activity of squalene epoxidase. Moreover this enzyme cooperates with subsequent enzymes like lanosterol synthase to facilitate the continuation of sterol biosynthesis.

Dysregulation of squalene epoxidase can lead to conditions such as hypercholesterolemia which is associated with elevated cholesterol levels and cardiovascular disease. This enzyme's malfunction is also implicated in certain dermatological disorders due to disrupted sterol metabolism affecting skin barrier function. Alterations in squalene epoxidase activity can influence the expression and function of other proteins like HMG-CoA reductase which is tightly regulated by feedback mechanisms in response to intracellular cholesterol levels.
