Product Overview
This rabbit polyclonal antibody recognizes protein O-glucosyltransferase 3 (gene POGLUT3) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 58.6 kDa, and the supplier reports an observed band at about 68 kDa.
Protein O-glucosyltransferase 3 (POGLUT3) is an ER enzyme that attaches glucose to a serine within a defined motif in certain EGF-like repeats. Reported substrates include NOTCH1, NOTCH3, fibrillins and LTBP1. The modification may help these proteins reach the cell surface, linking POGLUT3 to Notch signaling and extracellular matrix research.

Immunogen
Recombinant human POGLUT3 fragment (Arg48–Arg499), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places protein O-glucosyltransferase 3 in the endoplasmic reticulum lumen. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
