Gene Group (FlyBase)
PIEZO PROTEINS -
Piezo proteins are an evolutionarily conserved ion channel family involved in mechanotransduction. (Adapted from FBrf0217754).
Protein Function (UniProtKB)
Component of a mechanosensitive channel required for rapidly adapting mechanically activated (MA) currents (PubMed:22343900, PubMed:22343891). Plays a major role in nociception (response to strong or painful touch) (PubMed:22343891).
(UniProt, M9MSG8)
Summary (Interactive Fly)

mechanically activated cation channel - stretch-activated mechanotransduction - mechanical nociceptor
