Recombinant Human GCNT2 His-tag Protein/GCNT2 Enzyme Activity Diagram.

GCNT2 (Catalog # 10847-GT) recognizes polylactosamine structure and can tolerate core-6 fucose and its Cy5 derivatives.

Recombinant Human GCNT2 His-tag Protein, CF SDS-PAGE

1 μg/lane of Recombinant Human GCNT2 His-tag (Catalog # 10847-GT) was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing bands at 53-63 kDa.

Recombinant Human GCNT2 His-tag Protein, CF Fluorescent Gel Mobility Shift

Lane 1 contained substrate glycan extended G2 (GL303). In the presence of rhGCNT2, the glycan was modified, and a mobility shift was observed.

Background: Glucosaminyl (N-acetyl) Transferase 2/GCNT2

N-acetyllactosaminide beta-1,6-N-acetylglucosaminyl-transferase (GCNT2) is a key branching enzyme that converts linear into branched poly-N-acetyllactosaminoglycans. It is responsible for the formation of the blood group I antigens during embryonic development and is closely associated with the development and maturation of erythroid cells (1, 2, 3). GCNT2 is a Golgi resident type II membrane protein with a typical domain structure of glycosyltransferases. GCNT2 has been found to be downregulated in melanomas, which leads to the loss of N-linked I-branched glycans and the synthesis of poly-N-acetyllactosamine (i-linear) glycans (4). In addition, GCNT2 has been found to play a role in breast cancer and lung cancer and knockdown of GCNT2 expression decreased cell migration and invasion in vitro (5). The activity of recombinant GCNT2 is demonstrated in an electrophoretic gel mobility shift assay using a fluorophore-labeled glycan as the substrate (6).
