Recombinant Human Carbohydrate sulfotransferase 6 (CHST6), Truncated

Uniprot Id

Q9GZX3

Target Species

Human

Target Name

CHST6

Target Full Name

Carbohydrate sulfotransferase 6

Target Function

Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine (GlcNAc) residues of keratan. Cooperates with B4GALT4 galactosyltransferase and B3GNT7 N-acetylglucosaminyltransferase to construct and elongate the sulfated disaccharide unit [->3Galbeta1->4(6-sulfoGlcNAcbeta)1->] within keratan sulfate polymer. Involved in biosynthesis of keratan sulfate in cornea, with an impact on proteoglycan fibril organization and corneal transparency. Involved in sulfation of endothelial mucins such as GLYCAM1.

Target Involvement

Macular dystrophy, corneal (MCD)

Target Subcellular Location

Golgi apparatus membrane; Single-pass type II membrane protein.

Target Protein Families

Sulfotransferase 1 family, Gal/GlcNAc/GalNAc subfamily

Target Tissue Specificity

Expressed in cornea. Mainly expressed in brain. Also expressed in spinal cord and trachea.

Target Background

The protein encoded by this gene is an enzyme that catalyzes the transfer of a sulfate group to the GlcNAc residues of keratan. Keratan sulfate helps maintain corneal transparency. Defects in this gene are a cause of macular corneal dystrophy (MCD).
