Automated description from the Alliance of Genome Resources
Exhibits beta-galactoside (CMP) alpha-2,3-sialyltransferase activity. Involved in protein glycosylation. Predicted to localize to the Golgi apparatus and integral component of membrane. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability and early infantile epileptic encephalopathy 15. Is expressed in several structures, including alimentary system; central nervous system; cranium; eye; and hemolymphoid system gland. Orthologous to human ST3GAL3 (ST3 beta-galactoside alpha-2,3-sialyltransferase 3).
