Piezo1 / TRP channels
Name: Piezo-type mechanosensitive ion channel component 1
(Piezo1)
Official Symbol: PIEZO1
provided by HGNC
Function:
Pore-forming subunit of a mechanosensitive non-specific cation channel, that conducts both sodium and potassium ions. Plays a key role in epithelial cell adhesion by maintaining integrin activation through R-Ras recruitment to the ER, most probably in its activated state, and subsequent stimulation of calpain signaling.
