Protein attributes
| Sequence length | 491 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Potassium channel subunit. Modulates channel activity and reduces the ion flow By similarity. |
| Subunit structure | Heteromultimer with KCNB1 and with KCNB2. Does not form homomultimers. Might also bind to other channel proteins By similarity. |
| Subcellular location | Cell membrane; Multi-pass membrane protein By similarity. |
| Domain | The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position By similarity. |
| Sequence similarities | Belongs to the potassium channel family. S (TC 1.A.1.2) subfamily. Kv9.3/KCNS3 sub-subfamily. [View classification] |
