The membrane binding of the cytoplasmic domains increases as the net charge of the protein increases. The filled and empty symbols are the logarithmic values of the molar partition coefficients K (M-1) determined from experimental measurements of the binding of ζcyt (net charge of +5), FcεRIγcyt (net charge of +3), CD3εcyt (net charge of +11) as well as fully phosphorylated ζcyt (net charge of -5.5) and FcεRIγcyt (net charge of -0.5) to POPG (filled symbols) and 1:1 POPG/POPC (empty symbols) LUV in 1 mM MOPS, 100 mM KCl, pH 7.0. * Estimated from the curve fit.
