The protein encoded by this gene is a type II membrane
protein that catalyzes the transfer of sialic acid from CMP-sialic
acid to galactose-containing substrates. The encoded protein
prefers glycoproteins rather than glycolipids as substrates and
shows restricted substrate specificity, utilizing only the
trisaccharide sequence Neu5Ac-alpha-2,3-Gal-beta-1,3-GalNAc. In
addition, it is involved in the synthesis of ganglioside GD1A from
GM1B. The encoded protein is normally found in the Golgi apparatus
but can be proteolytically processed to a soluble form. This
protein is a member of glycosyltransferase family 29. Transcript
variants encoding different isoforms have been found for this gene.1) Yoshino, H., et al. Brain Res. 1227, 216-220 (2008) :
