* This is a Type II Golgi enzyme that aids the biosynthesis of Keratin sulfates (KS).
* KS is a major component of articular cartilage and cornea, while various KS proteins are also found in other tissues and cells.
* B3GNT7 preferentially acts to on sulfated type 2 glycans (Galβ1-4(SO3-6)GlcNAcβ1-3Galβ1-4(SO3-6)GlcNAc).
* It works in concert with CHST6 and B4GalT4 to extend KS polyLacNAc chains, and its function is reduced upon Gal-sulfation by CHST1.
* B3GNT7 is upregulated during ovarian cancer. It results in the expression of the HMOCC-1 mAb epitope.
