Sequence Features
| 37 | Essential for channel activity, possibly by being protonated during channel activation, and by forming the channel gate and the selective filter | ||
| 41 | Seems to be involved in pH gating | ||
| 17 | Interchain (with C-17) | ||
| 19 | Interchain (with C-19) | ||
| 23-43 | Helical; Signal-anchor for type III membrane protein | ||
| 1-97 | Influenza virus matrix protein 2 IPR002089PF00599 |
