These results demonstrate that the SEP tag enables the rapid production of the multiple disulfide-bonded EGFR-ECDIII in E. coli having native-like biophysical properties and producing neutralizing antibodies.Desmin, an intermediate filament protein expressed in muscle cells, plays a key role in the integrity and regulation of the contractile system. Furthermore, the distribution of desmin in cells and its interplay with plasma and organelle membranes are crucial for cell functions; however, the fundamental properties of lipid-desmin interactions remain unknown. Using a water-in-oil method for a limited space system in vitro, we examined the distribution of desmin in three types of phospholipid droplets 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), and 1,2-dioleoyl-sn-glycero-3-phosphoserine (DOPS). When fluorescent-labeled desmin was observed for 60 min after desmin assembly was initiated by adding 25 mM KCl, desmin accumulated on both the DOPE and DOPS layers; however, it did not accumulate on the DOPC layer of droplets. An increase in salt concentration did not moderate the accumulation. The initial form of either oligomer or mature filament affected the accumulation on each lipid layer. When liposomes were included in the droplets, desmin was associated with DOPE but not on DOPC liposomes. These results suggest that desmin has the potential for association with phospholipids concerning desmin form and lipid shape. The behavior and composition of living membranes may affect the distribution of desmin networks.VbrK and VbrR from the gastroenteritis-causing Vibrio parahaemolyticus are a histidine kinase and response regulator, respectively, that constitute a two-component regulatory system. VbrK responds to β-lactam antibiotics or nitrate and act
