SMrT screen to identify membrane fission catalysts. (A) Schematic of supported membrane tubes (SMrT) and a supported lipid bilayer (SLB). (B) Tube radius distribution on PEG400- and PEG8000-functionalized glass coverslips. Data represent means ± the standard deviation (SD) for the indicated numbers of tubes. (C) Plot showing membrane-bound mEGFP-LactC2 with increasing bulk protein concentrations. Data represent the mean ± SD for n ≥ 10 tubes analyzed for each protein concentration. (D) Micrographs of DOPC/DOPS/p-Texas Red DHPE SMrT templates (49:50:1 molar ratio) acquired in the Texas Red channel in the absence and presence of excess LactC2 domain. The scale bar is 10 μm.
