Anti-UBIAD1 Antibody

The UbiA prenyltransferase domain containing 1 (UBIAD1) protein , also known as TERE1, was initially identified as a down-regulated gene in transitional cell carcinoma of the bladder (1) . Recently it has been shown to bind the cholesterol carrier APOE and modulate cellular cholesterol levels (2) . Mutations in the UBIAD1 gene can cause Schnyder crystalline corneal dystrophy, an autosomal dominant disease characterized by progressive opacification of the cornea resulting from the local accumulation of lipids (3) .

UBIAD1 antibody was raised against a 15 amino acid peptide near the carboxy terminus of human UBIAD1. The immunogen is located within amino acids 210 - 260 of UBIAD1.

Prenyltransferase that mediates the formation of menaquinone-4 (MK-4) and coenzyme Q10. MK-4 is a vitamin K2 isoform present at high concentrations in the brain, kidney and pancreas, and is required for endothelial cell development. Mediates the conversion of phylloquinone (PK) into MK-4, probably by cleaving the side chain of phylloquinone (PK) to release 2- methyl-1,4-naphthoquinone (menadione; K3) and then prenylating it with geranylgeranyl pyrophosphate (GGPP) to form MK-4. Also plays a role in cardiovascular development independently of MK-4 biosynthesis, by acting as a coenzyme Q10 biosynthetic enzyme: coenzyme Q10, also named ubiquinone, plays a important antioxidant role in the cardiovascular system. Mediates biosynthesis of coenzyme Q10 in the Golgi membrane, leading to protect cardiovascular tissues from NOS3/eNOS-dependent oxidative stress.
