Anti-FAM38A/PIEZO1 antibody [EPR23826-103],Abcam,AB259949

Target data Pore-forming subunit of the mechanosensitive non-specific cation Piezo channel required for rapidly adapting mechanically activated (MA) currents and has a key role in sensing touch and tactile pain (PubMed : 23479567, PubMed : 23695678, PubMed : 25955826, PubMed : 37590348). Piezo channels are homotrimeric three-blade propeller-shaped structures that utilize a cap-motion and plug-and-latch mechanism to gate their ion-conducting pathways (PubMed : 37590348). Generates currents characterized by a linear current-voltage relationship that are sensitive to ruthenium red and gadolinium (By similarity). Conductance to monovalent alkali ions is highest for K(+), intermediate for Na(+) and lowest for Li(+) (PubMed : 25955826). Divalent ions except for Mn(2+) permeate the channel but more slowly than the monovalent ions and they also reduce K(+) currents (PubMed : 25955826). 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 inner ear hair cells, PIEZO1/2 subunits may constitute part of the mechanotransducer (MET) non-selective cation channel complex where they may act as pore-forming ion-conducting component in the complex (By similarity). In the kidney, may contribute to the detection of intraluminal pressure changes and to urine flow sensing (By similarity). Acts as a 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). Acts as a sensor of phosphatidylserine (PS) flipping at the plasma membrane and governs morphogenesis of muscle cells (By similarity). 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 (PubMed : 29799007).
