PIEZO1 antibody

Pore-forming subunit of a mechanosensitive non-specific cation channel (PubMed:23479567, PubMed:23695678) . Generates currents characterized by a linear current-voltage relationship that are sensitive to ruthenium red and gadolinium. 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 (PubMed:20016066) . In the kidney, may contribute to the detection of intraluminal pressure changes and to urine flow sensing. Acts as shear-stress sensor that promotes endothelial cell organization and alignment in the direction of blood flow through calpain activation (PubMed:25119035) . Plays a key role in blood vessel formation and vascular structure in both development and adult physiology (By similarity) .
