General annotation (Comments)
| Function | Component of mechanosensitive channel required for rapidly adaptating mechanically activated (MA) currents in DRG neurons By similarity. |
| Subcellular location | Membrane; Multi-pass membrane protein Potential. |
| Miscellaneous | Piezo comes from the Greek 'piesi' meaning pressure. |
| Sequence similarities | Belongs to the PIEZO family. |
| Sequence caution | The sequence BAB15556.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAB15556.1 differs from that shown. Reason: Erroneous termination at position 2718. Translated as Arg. The sequence BAB15641.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAC03832.1 differs from that shown. Reason: Unlikely isoform. Aberrant splice sites. The sequence BAC05412.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAC05412.1 differs from that shown. Reason: Contaminating sequence at the 3'end. Probable cloning artifact. |
