Protein attributes
| Sequence length | 437 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Component of the sarcoglycan complex, a subcomplex of the dystrophin-glycoprotein complex which forms a link between the F-actin cytoskeleton and the extracellular matrix. |
| Subcellular location | Cell membrane › sarcolemma; Single-pass membrane protein Potential. Cytoplasm › cytoskeleton By similarity. |
| Tissue specificity | Ubiquitous. |
| Involvement in disease | Dystonia 11 (DYT11) [MIM:159900]: A myoclonic dystonia. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures. DYT11 is characterized by involuntary lightning jerks and dystonic movements and postures alleviated by alcohol. Inheritance is autosomal dominant. The age of onset, pattern of body involvement, presence of myoclonus and response to alcohol are all variable. |
| Sequence similarities | Belongs to the sarcoglycan alpha/epsilon family. |
| Sequence caution | The sequence AAC04368.1 differs from that shown. Reason: Erroneous initiation. |
