Clone Names | 91208086 |
Gene ID | 6307 |
---|---|
Other Names | Methylsterol monooxygenase 1, C-4 methylsterol oxidase, MSMO1, DESP4, ERG25, SC4MOL |
Target/Specificity | The synthetic peptide sequence used to generate the antibody AP13954b was selected from the C-term region of ERG25. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay. |
Format | Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed. |
Storage | Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C. |
Precautions | This product is for research use only. Not for use in diagnostic or therapeutic procedures. |
Name | MSMO1 |
---|---|
Synonyms | DESP4, ERG25, SC4MOL |
Function | Catalyzes the three-step monooxygenation required for the demethylation of 4,4-dimethyl and 4alpha-methylsterols, which can be subsequently metabolized to cholesterol (PubMed:21285510, PubMed:23583456, PubMed:26114596, PubMed:28673550, PubMed:36958722). Also involved in drug metabolism, as it can metabolize eldecalcitol (ED-71 or 1alpha,25-dihydroxy-2beta-(3-hydroxypropoxy)- cholecalciferol), a second-generation vitamin D analog, into 1alpha,2beta,25-trihydroxy vitamin D3; this reaction occurs via enzymatic hydroxylation and spontaneous O-dehydroxypropylation (PubMed:26038696). |
Cellular Location | Endoplasmic reticulum membrane; Multi-pass membrane protein |

Background
Sterol-C4-mehtyl oxidase-like protein was isolated basedon its similarity to the yeast ERG25 protein. It contains a set ofputative metal binding motifs with similarity to that seen in afamily of membrane desaturases-hydroxylases. The protein islocalized to the endoplasmic reticulum membrane and is believed tofunction in cholesterol biosynthesis. Alternatively splicedtranscript variants encoding distinct isoforms have been found forthis gene.
