Summary: Enables beta-galactoside alpha-2,6-sialyltransferase activity. Involved in neuromuscular junction development and oligosaccharide metabolic process. Located in Golgi apparatus and extracellular region. Is expressed in organism and presumptive embryonic salivary gland. Orthologous to several human genes including ST6GAL1 (ST6 beta-galactoside alpha-2,6-sialyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

DSiaT mutations result in decreased life span, locomotor abnormalities, temperature-sensitive paralysis, and defects of neuromuscular junctions. DSiaT regulates neuronal excitability and affects function of a voltage-gated sodium channel.
Title: Sialyltransferase regulates nervous system function in Drosophila.
This gene encodes a functional alpha2-6-sialyltransferase (SiaT) that is closely related to the vertebrate ST6Gal sialyltransferase family, indicating an ancient evolutionary origin for this family.
