Piezo-type mechanosensitive ion channel component 2 is a protein that in humans is encoded by the PIEZO2 gene .[ 5] It has a homotrimeric structure, with three blades curving into a nano-dome, with a diameter of 28 nanometers.[ 6]

Piezos are large transmembrane proteins conserved among various species, all having between 24 and 36 predicted transmembrane domains . 'Piezo' comes from the Greek 'piesi,' meaning 'pressure.' The PIEZO2 protein has a role in rapidly adapting mechanically activated (MA) currents in somatosensory neurons.[ 7] Its structure is resolved via a mouse version in 2019, showing the predicted homotrimeric propeller.[ 8]
PIEZO2 is typically found in cell types that respond to physical touch, such as Merkel cells ,[ 9] and is thought to regulate light touch response.[ 10]
