Protein attributes
| Sequence length | 756 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Glycosyltransferase which participates in glycosylation of alpha-dystroglycan. May carry out the synthesis of glycoprotein and glycosphingolipid sugar chains. May be involved in the addition of a repeated disaccharide unit. |
| Pathway | |
| Subcellular location | Golgi apparatus membrane; Single-pass type II membrane protein. |
| Tissue specificity | Ubiquitous. Highest expression in heart, brain and skeletal muscle. |
| Involvement in disease | Defects in LARGE are the cause of congenital muscular dystrophy type 1D (MDC1D) [MIM:608840]. The congenital muscular dystrophies (CMD) are a heterogeneous group of autosomal recessive disorders presenting in infancy with muscle weakness, contractures, and dystrophic changes on skeletal muscle biopsy. Structural brain defects, with or without mental retardation, are additional features of several CMD syndromes. MDC1D presented with congenital muscular dystrophy, profound mental retardation, and white matter changes and subtle structural abnormalities on brain MRI. Patient skeletal muscle biopsy showed reduced immunolabeling of alpha-dystroglycan. |
| Sequence similarities | Belongs to the glycosyltransferase 8 family. |
