Status
Functioni
Isoform 1: Possible multifunctional enzyme with both glycosyltransferase and deubiquitinase activities.
Isoform 2: May be involved in protein N-glycosylation, second step of the dolichol-linked oligosaccharide pathway.
Catalytic activityi
- N-acetyl-α-D-glucosaminyl-diphosphodolichol + UDP-N-acetyl-α-D-glucosamine = H+ + N,N'-diacetylchitobiosyl diphosphodolichol + UDPEC:2.4.1.141
- Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal). EC:3.4.19.12

Involvement in diseasei
Epileptic encephalopathy, early infantile, 36 (EIEE36)5 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. Some EIEE36 patients may present with an abnormal isoelectric focusing of serum transferrin, consistent with a diagnostic classification of congenital disorder of glycosylation type I. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions.
