Amino acid sequence homology between S protein and mFcγRII regions. (A) A scheme showing the homologous regions of S protein and mFcgRII receptor in positions 546–548, 554–556 and 581–586 (lower case letters). (B) A comparison between the predicted secondary structures of the binding domains of murine Fcγ receptor type II, mFcγR (Panel A) and the homologous regions of spike protein of MHV/A59 (Panel B) predicted by PSIPRED (http://bioinf.cs.ucl.ac.uk/psipred). The H stands for helix, C for coil and E for strand. The bars for each amino acid represent the confidence of each prediction. The taller the bar is, the higher the confidence. The amino acid sequences of the short regions of sequence similarity in the two structures are underlined similarly.
