Rabbit anti-Human Cytochrome P450 7B1 Polyclonal Antibody | anti-CYP7B1 antibody
Anti-Cytochrome P450 7B1 Antibody
Western Blot (WB)
(Western blot analysis of Cytochrome P450 7B1 expression in Hela (A), A549 (B), MCF7 (C) whole cell lysates.)
Immunohistochemistry (IHC)
(Immunohistochemical analysis of Cytochrome P450 7B1 staining in human prostate cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.)
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This endoplasmic reticulum membrane protein catalyzes the first reaction in the cholesterol catabolic pathway of extrahepatic tissues, which converts cholesterol to bile acids. This enzyme likely plays a minor role in total bile acid synthesis, but may also be involved in the development of atherosclerosis, neurosteroid metabolism and sex hormone synthesis.

Uniprot Description
CYP7B1: Defects in CYP7B1 are the cause of spastic paraplegia autosomal recessive type 5A (SPG5A). Spastic paraplegia is a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. Defects in CYP7B1 are the cause of congenital bile acid synthesis defect type 3 (CBAS3). Clinical features include severe cholestasis, cirrhosis and liver synthetic failure. Hepatic microsomal oxysterol 7-alpha-hydroxylase activity is undetectable. Belongs to the cytochrome P450 family.
