Functioni

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 (PubMed:21081508, PubMed:21490058, PubMed:21949356, PubMed:27807076, PubMed:28775322). Specifically targets extracellular EGF repeats of protein such as CRB2, F7, F9 and NOTCH2 (PubMed:21081508, PubMed:21490058, PubMed:21949356, PubMed:27807076, PubMed:28775322). Acts as a positive regulator of Notch signaling by mediating O-glucosylation of Notch, leading to regulate muscle development (PubMed:27807076). Notch glucosylation does not affect Notch ligand binding (PubMed:21490058). 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).By similarity5 Publications

Involvement in diseasei

Dowling-Degos disease 4 (DDD4)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of Dowling-Degos disease, a genodermatosis manifesting with postpubertal reticulate hyperpigmentation that is progressive and disfiguring, and small hyperkeratotic dark brown papules that affect mainly the flexures and great skin folds. Patients usually show no abnormalities of the hair or nails. DDD4 is characterized by prominent involvement of non-flexural skin areas.

Limb-girdle muscular dystrophy 2Z (LGMD2Z)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of autosomal recessive limb-girdle muscular dystrophy, a degenerative myopathy characterized by slowly progressive wasting and weakness of the proximal muscles of arms and legs around the pelvic or shoulder girdles, elevated creatine kinase levels and dystrophic features on muscle biopsy. LGMD2Z is characterized by young-adult onset.
