Anti-CYP4X1 antibodies are used in the immunodetection of the protein cytochrome P450 family 4 subfamily X member 1. In humans, the canonical protein has a reported length of 509 amino acid residues and a mass of 58.9 kDa. Its subcellular localization is in the ER. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in the brain, heart, kidney and skin and, at lower levels, in skeletal muscle and liver. A member of the Cytochrome P450 protein family, CYP4X1 is a cytochrome P450 monooxygenase that selectively catalyzes the epoxidation of the last double bond of the arachidonoyl moiety of anandamide, potentially modulating endocannabinoid signaling. Synonyms for this target antigen include cytochrome P450 4X1 and cytochrome P450, family 4, subfamily X, polypeptide 1. CYP4X1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the CYP4X1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
