Rabbit anti-Human ST3GAL3 Polyclonal Antibody

Uniprot Id

Q11203

Target Species

Human

Target Name

ST3GAL3

Target Full Name

CMP-N-acetylneuraminate-beta-1,4-galactoside alpha-2,3-sialyltransferase

Target Function

Catalyzes the formation of the NeuAc-alpha-2,3-Gal-beta-1,4-GlcNAc-, NeuAc-alpha-2,3-Gal-beta-1,3-GlcNAc- and NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc- sequences found in terminal carbohydrate groups of glycoproteins and glycolipids. The highest activity is toward Gal-beta-1,3-GlcNAc and the lowest toward Gal-beta-1,3-GalNAc.

Target Involvement

Mental retardation, autosomal recessive 12 (MRT12); Epileptic encephalopathy, early infantile, 15 (EIEE15)

Target Subcellular Location

Golgi apparatus, Golgi stack membrane; Single-pass type II membrane protein. Secreted. Note=Membrane-bound form in trans cisternae of Golgi. Secreted into the body fluid.

Target Protein Families

Glycosyltransferase 29 family

Target Tissue Specificity

Highly expressed in adult skeletal muscle and in all fetal tissues examined and to a much lesser extent in placenta, lung and liver.

Target Research Area

Signal Transduction

Target Background

The protein encoded by this gene is a type II membrane protein that catalyzes the transfer of sialic acid from CMP-sialic acid to galactose-containing substrates. The encoded protein is normally found in the Golgi apparatus but can be proteolytically processed to a soluble form. This protein is a member of glycosyltransferase family 29. Mutations in this gene have been associated with a form of autosomal recessive nonsymdromic cognitive disability as well as infantile epileptic encephalopathy. Multiple transcript variants encoding several different isoforms have been found for this gene.
