ST8SIA6 (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 6)

Gene

• Entrez ID: 338596
• Gene name: ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 6
• Gene symbol: ST8SIA6
• Synonyms (NCBI Gene): SIA8F, SIAT8-F, SIAT8F, ST8SIA-VI, ST8SiaVI
• Chromosome: 10
• Chromosome location: 10p12.33
• Summary: This gene encodes a member of the glycosyltransferase 29 protein family. Members of this protein family synthesize sialylglycoconjugates. Sialylation may contribute to multidrug resistance in cancer cells. Alternative splicing results in multiple transcri
