一般描述

MGAT4A (mannosyl (α-1,3-)-glycoprotein β-1,4-N-acetylglucosaminyltransferase, isozyme A) gene is mapped to human chromosome 2q12. The enzyme contains 535-aminoacids and is encoded by an mRNA having 16 exons interspaced by 15 introns. It is predominantly expressed in spleen, thymus, peripheral blood leukocytes, lymph node, prostate, pancreas, and small intestine.

应用

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

生化/生理作用

MGAT4A (mannosyl (α-1,3-)-glycoprotein β-1,4-N-acetylglucosaminyltransferase, isozyme A) gene encodes a glycosyltransferase that mediates the formation of tri- and multiantennary branching structures on membrane proteins in the Golgi apparatus. The enzyme catalyzes the transfer of N-acetylglucosamine (GlcNAc) from UDP-GlcNAc in a β-1,4 linkage to the core mannose residues of N-linked glycans. It mediates GLUT2 glycosylation and facilitates the transport of glucose by pancreatic β cells. Increased levels of this protein is observed in white cells of peripheral blood of Type 2 diabetes patients. The enzyme is involved in the regulation of the availability of serum glycoproteins, oncogenesis, and cell differentiation.

特点和优势

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
