Background
| Function | FUNCTION: Catalyzes the addition of sialic acid in alpha 2,8-linkage to the sialic acid moiety of the ganglioside GM3 to form ganglioside GD3; gangliosides are a subfamily of complex glycosphinglolipds that contain one or more residues of sialic acid (PubMed:7937974, PubMed:8058740, PubMed:8195250, PubMed:8631981, PubMed:8706663, PubMed:18348864, PubMed:22885356). Can catalyze the addition of a second alpha-2,8-sialic acid to GD3 to form GT3 (PubMed:8631981). Can use GM1b, GD1a and GT1b as acceptor substrates to synthesize GD1c, GT1a and GQ1b respectively (PubMed:8706663). Can synthesize unusual tetra- and pentasialylated lactosylceramide derivatives identified as GQ3 (II3Neu5Ac4-Gg2Cer) and GP3 (II3Neu5Ac5-Gg2Cer) in breast cancer cells (PubMed:22885356). {ECO:0000269|PubMed:18348864, ECO:0000269|PubMed:22885356, ECO:0000269|PubMed:7937974, ECO:0000269|PubMed:8058740, ECO:0000269|PubMed:8195250, ECO:0000269|PubMed:8631981, ECO:0000269|PubMed:8706663}. |
| Pathway | Protein modification; protein glycosylation. Lipid metabolism; sphingolipid metabolism. |
| Protein Families | Glycosyltransferase 29 family |
| Tissue Specificity | Strongly expressed in melanoma cell lines, adult and fetal brain and to a lesser extent in adult and fetal lung. {ECO:0000269|PubMed:7937974, ECO:0000269|PubMed:8631981}. |
