Protein Structure
UniProt Annotation
Function Alpha-2,6-sialyltransferase involved in the synthesis of alpha-series gangliosides. Has activity toward GD1a, GT1b and GM1b. Has no activity toward glycoproteins. Responsible for the biosynthesis of DSGG (disialylgalactosylgloboside) from MSGG (monosialylgalactosylgloboside) in normal and malignant kidney. Participates in the synthesis of disialyl Lewis a (Le(a)). {ECO:0000269PubMed:12668675, ECO:0000269PubMed:17123352}.
Subcellular Localization Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}.
Disease Associations
Tissue Specificity Expressed in kidney, in proximal tubule epithelial cells. Expressed in colon cell lines. {ECO:0000269PubMed:12668675, ECO:0000269PubMed:17123352}.
