galactose-3-O-sulfotransferase 2; gal3ST-2; beta-galactose-3-O-sulfotransferase 2; gal-beta-1, 3-galNAc 3'-sulfotransferase 2; glycoprotein beta-gal 3'-sulfotransferase 2 (GAL3ST2, GP3ST)

Function: - transfers a sulfate group to the hydroxyl group at C3 of non-reducing beta-galactosyl residues - acts both on type 1 (gal-beta-1,3-GlcNAc) & type 2 (gal-beta-1,4-GlcNAc) chains with similar efficiency - protein modification; carbohydrate sulfation Kintetic parameters: - pH dependence: optimum pH is 6.0-6.5 Inhibition: - strongly inhibited by Cu+2 & Zn+2 Structure: belongs to the galactose-3-O-sulfotransferase family Compartment: - Golgi, Golgi stack membrane - single-pass type 2 membrane protein (probable) Expression: - ubiquitous - detected in heart, stomach, colon, liver & spleen, placenta, renal tubules, & neurons of the cerebral cortex
