Anti-SPG5A antibodies enable researchers to detect and measure the SPG5A antigen in biological samples. This target is a reported synonym of the CYP7B1 gene, which encodes cytochrome P450 family 7 subfamily B member 1. This protein is known to function in cholesterol metabolism and homeostasis, among other biological roles. The human version of SPG5A has a canonical amino acid length of 506 residues and a protein mass of 58.3 kilodaltons. It is reported to be localized in the ER of cells. Other names for this target antigen include CBAS3 and CP7B.
