Protein attributes
| Sequence length | 881 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May function to confer stability and plasticity to neuronal membrane via multiple interactions, including the spectrin-actin-based cytoskeleton, integral membrane channels and membrane-associated guanylate kinases. |
| Subunit structure | Interacts with AGAP2. Ref.6 |
| Subcellular location | |
| Tissue specificity | Highest expression in brain, lower in heart, kidney, pancreas, placenta, lung and skeletal muscle. |
| Involvement in disease | Mental retardation, autosomal dominant 11 (MRD11) [MIM:614257]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. |
| Sequence similarities | Contains 1 FERM domain. |
| Sequence caution | The sequence BAA20796.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
