PIEZO2

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]

Function

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]

Pathology

• Gain-of-function mutations in the mechanically activated ion channel PIEZO2 cause a subtype of Distal Arthrogryposis.[8]
• Recent studies show that the congenital atrophy in PIEZO2 leads to not having self perception of extremities, and so the distortion in the response to touch (where the response was linked to an emotional response rather than a physical one). It was performed with two patients who would not be able to attempt to coordinate their movements without visually doing it, nor could they know where their extremities were at.
• PIEZO2 mutations link Gordon syndrome (distal arthrogryposis type 3), Marden-Walker syndrome and Arthrogryposis (Distal Arthrogryposis Type 5).[9]
