NN, NC, CN, CC indicates the nature of fusion proteins by which an interaction was or not detected (+ or −, respectively). Redundant PPI in Y2H: Interactions that could be potentially reproduced by a) more than one vector pairing, b) reciprocal interaction (r, found in both bait-prey and prey-bait orientation) or c) overlapping constructs (indicated by their consecutive number). Possible only if the constructs P, V, X or Pvx are involved. (s): Self-interaction. The quality of interactions was classified from “high quality” to “basic quality”. “high quality”: Redundant interaction found in Y2H and LuMPIS. “medium quality”: Redundant interaction found in Y2H or LuMPIS. “basic quality”: No redundant interaction detected. Interactions No. 15, 17 and 30 were detected by combinations of C-terminal tagged proteins.
