( +): interactions have been detected, at least with one method; (−): no interaction could be detected. Fraction numbers indicate the numbers of methods showing interactions over the total number of methods used. Superscript letters refer to the detection method: (a) MC-Mal (this study); (b) LB-X-Gal (this study); (c) M63-Mal (this study); (d) cross-linking (this study); (e) MC-Mal²⁹; (f) LB-X-Gal²⁹; (g) M63-Mal²⁹;(h) SEC²⁹.
