| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Isoform 2 may be involved in protein N-glycosylation, second step of the dolichol-linked oligosaccharide pathway. Ref.7 |
| Catalytic activity | UDP-N-acetyl-D-glucosamine + N-acetyl-D-glucosaminyl-diphosphodolichol = UDP + N,N'-diacetylchitobiosyl-diphosphodolichol. |
| Subunit structure | Isoform 2 may interact with ALG14 By similarity. |
| Subcellular location | Isoform 2: Endoplasmic reticulum Probable. Note: Could be recruited to the cytosolic face of the endoplasmic reticulum membrane through its interaction with ALG14. |
| Involvement in disease | 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. |
| Sequence similarities | Belongs to the glycosyltransferase 28 family. Contains 1 OTU domain. Contains 1 Tudor domain. |
| Sequence caution | The sequence AAI17378.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAI17380.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAB15521.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAD96874.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAH14244.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAH14244.1 differs from that shown. Reason: Erroneous termination at position 424. Translated as Cys. The sequence CAI43016.2 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAM28219.1 differs from that shown. Reason: Erroneous gene model prediction. |
