Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Isoform 2: Endoplasmic reticulum {ECO:0000305}. Note=Could be recruited to the cytosolic face of the endoplasmic reticulum membrane through its interaction with ALG14.

Disease Associations

Congenital disorder of glycosylation 1S (CDG1S) [MIM:300884]: A multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. 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. {ECO:0000269PubMed:22492991}. Note=The disease is caused by mutations affecting the gene represented in this entry.
