Summary
Enables sialyltransferase activity. Involved in several processes, including negative regulation of macrophage apoptotic process; protein sialylation; and regulation of substrate adhesion-dependent cell spreading. Located in Golgi medial cisterna and Golgi trans cisterna. Used to study high grade glioma. Orthologous to human ST6GAL1 (ST6 beta-galactoside alpha-2,6-sialyltransferase 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
