Description
Reduced NotchR signaling has been implicated in the reduced division and differentiation of stem cells in a number of tissues. The Protein-O-fucosyltransferase 1 gene (Pofut1) encodes a glycosyltransferase that O-fucosylates EGF-repeat-containing proteins, including Notch Receptors (NotchRs), and absence of Pofut1 glycosylation on NotchRs inhibits ligand-induced NotchR signaling.
