胆固醇25α7羟化酶抗体概述：

B淋巴细胞在抗原的刺激下，能够分化、增殖形成具有针对这种抗原分泌特异性抗体的能力。B细胞的这种能力和量是有限的，不可能持续分化增殖下去，因此产生免疫球蛋白的能力也是极其微小的。将这种B细胞与非分泌型的骨髓瘤细胞融合形成杂交瘤细胞，再进一步克隆化，这种克隆化的杂交瘤细胞是既具有瘤细胞的无限分裂的能力，又具有产生特异性抗体的B淋巴细胞的能力。将这种克隆化的杂交瘤细胞进行培养或注入小鼠腹水内即可获得大量的高效、单一的特异性抗体。这种技术即称为单克隆抗体技术。

产品介绍 The CYP7B1 protein catalyzes the first reaction in the cholesterol catabolic pathway of extrahepatic tissues, which converts cholesterol to bile acids. This enzyme is likely to play a minor role in total bile acid synthesis, and may also be involved in the development of neurosteroid metabolism, atherosclerosis and sex hormone synthesis, and is a member of the cytochrome P450 superfamily of enzymes.

Subcellular Location : Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein.

Tissue Specificity : Brain, testis, ovary, prostate, liver, colon, kidney, and small intestine.

DISEASE : Defects in CYP7B1 are the cause of spastic paraplegia autosomal recessive type 5A (SPG5A) [MIM:270800]. 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.

胆固醇25α7羟化酶抗体Defects in CYP7B1 are the cause of congenital bile acid synthesis defect type 3 (CBAS3) [MIM:613812]. Clinical features include severe cholestasis, cirrhosis and liver synthetic failure. Hepatic microsomal oxysterol 7-alpha-hydroxylase activity is undetectable.

Similarity : Belongs to the cytochrome P450 family.
