This enzyme adds O-fucose through an O-glycosidic linkage to conserved serine or threonine residues in the epidermal growth factor-like repeats of a number of cell surface and secreted proteins. O-fucose glycans are involved in ligand-induced receptor signaling. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Catalyzes the reaction that attaches fucose through an O-glycosidic linkage to a conserved serine or threonine residue found in the consensus sequence C2-X(4,5)-[S/T]-C3 of EGF domains, where C2 and C3 are the second and third conserved cysteines. Specifically uses GDP-fucose as donor substrate and proper disulfide pairing of the substrate EGF domains is required for fucose transfer. Plays a crucial role in NOTCH signaling. Initial fucosylation of NOTCH by POFUT1 generates a substrate for FRINGE/RFNG, an acetylglucosaminyltransferase that can then extend the fucosylation on the NOTCH EGF repeats. This extended fucosylation is required for optimal ligand binding and canonical NOTCH signaling induced by DLL1 or JAGGED1. Fucosylates AGRN and determines its ability to cluster acetylcholine receptors (AChRs). {ECO:0000269|PubMed:11524432, ECO:0000269|PubMed:28334865, ECO:0000269|PubMed:8358148}. |O-FucT| |peptide-O-fucosyltransferase activity| |protein O-linked fucosylation| |fucosyltransferase activity| |fucose metabolic process| |fucosylation| |O-glycan processing| |somitogenesis| |somite development| |segmentation| |regulation of Notch signaling pathway| |protein O-linked glycosylation| |Notch signaling pathway| |hexose metabolic process| |monosaccharide metabolic process| |anterior/posterior pattern specification| |macromolecule glycosylation| |protein glycosylation| |glycosylation| |angiogenesis| |glycoprotein biosynthetic process| |regionalization| |glycoprotein metabolic process| |blood vessel morphogenesis| |pattern specification process| |carbohydrate metabolic process| |blood vessel development| |vasculature development| |cardiovascular system development| |heart development| |carbohydrate derivative biosynthetic process| |chordate embryonic development| |embryo development ending in birth or egg hatching| |tube morphogenesis| |tube development| |circulatory system development| |anatomical structure formation involved in morphogenesis| |embryo development| |endoplasmic reticulum| |carbohydrate derivative metabolic process| |epithelium development| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |small molecule metabolic process| |tissue development| |macromolecule biosynthetic process| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp335|Aminopterin 0.005μM R07 exp335]]|-1.88| |[[:results:exp292|Menadione 5μM R06 exp292]]|1.77| |[[:results:exp293|Myriocin 25μM R06 exp293]]|2.01| No correlation found to any other genes in chemogenomics.
