Myelodysplastic syndromes relative protein; Dual specificity glycosyltransferase that catalyzes the transfer of glucose and xylose from UDP-glucose and UDP-xylose, respectively, to a serine residue found in the consensus sequence of C-X-S-X-P-C. Specifically targets extracellular EGF repeats of protein such as CRB2, F7, F9 and NOTCH2. Acts as a positive regulator of Notch signaling by mediating O-glucosylation of Notch, leading to regulate muscle development. Notch glucosylation does not affect Notch ligand binding. Required during early development to promote gastrulation: acts by mediating O- glucosylation of CRB2, which is required for CRB2 localization to the cell membrane (By similarity).
Synonyms: POGLUT1, POGLUT1p, hPOGLUT1, B4DJ97, B4DVA9 ...
