The preparation of the recombinant Human PIEZO1 protein involves manipulating the expression of the desired gene in e.coli cells. The sequence (2198-2431aa) of foreign DNA is fused to an expression vector and then introduced into e.coli cells. Selected positive cells are cultured to induce the expression of the desired protein. The protein features a N-terminal 10xHis tag and C-terminal Myc tag fusion. The recombinant targeted protein is subjected to affinity purification. Its purity exceeds 90% as assessed by SDS-PAGE.

Target Background

Pore-forming subunit of a mechanosensitive non-specific cation channel. 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. 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. Plays a key role in blood vessel formation and vascular structure in both development and adult physiology. Acts as sensor of phosphatidylserine (PS) flipping at the plasma membrane and governs morphogenesis of muscle cells. In myoblasts, flippase-mediated PS enrichment at the inner leaflet of plasma membrane triggers channel activation and Ca2+ influx followed by Rho GTPases signal transduction, leading to assembly of cortical actomyosin fibers and myotube formation.

  1. Both vertebrate and invertebrate mechanosensitive PIEZO ion channels are polymodal, being voltage modulated, and can even be directly voltage gated following a preceding mechanical stimulus. PMID: 29545531
  2. In the absence of extracellular matrix (ECM) proteins Piezo1 receptors are relatively insensitive to mechanical forces pushing the cellular membrane, whereas they can hardly be activated by mechanically pulling the membrane. Yet, if conjugated with Matrigel, a mix of ECM proteins, the receptors become sensitized. PMID: 28164706
