    Summary
    Enables beta-galactoside (CMP) alpha-2,3-sialyltransferase activity. Involved in several processes, including ganglioside biosynthetic process via lactosylceramide; memory B cell differentiation; and negative regulation of activated CD8-positive, alpha-beta T cell apoptotic process. Acts upstream of or within protein glycosylation and protein phosphorylation. Predicted to be located in Golgi medial cisterna membrane; Golgi trans cisterna membrane; and trans-Golgi network membrane. Predicted to be active in membrane. Is expressed in several structures, including alimentary system; ear; hemolymphoid system; integumental system; and nervous system. Orthologous to human ST3GAL1 (ST3 beta-galactoside alpha-2,3-sialyltransferase 1). [provided by Alliance of Genome Resources, Dec 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.
