Protein attributes
| Sequence length | 1253 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Seems to be involved in the assembly of the postsynaptic apparatus. May play a role in acetyl-choline receptor (AChR) aggregation in the postsynaptic membrane By similarity. Ref.1 |
| Subunit structure | Interacts with FLNC. Ref.1 |
| Subcellular location | Cytoplasm. Membrane; Peripheral membrane protein. Note: Translocates to the plasma membrane at high levels of PtdIns(3,4,5)P3. At low levels of PtdIns(3,4,5)P3 is translocated to vesicular compartments. Ref.1 |
| Domain | The PH domain mediates the binding to phosphoinositides. |
| Sequence similarities | Contains 1 PH domain. |
| Sequence caution | The sequence AAH69194.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence BAD93140.1 differs from that shown. Reason: Erroneous initiation. |
