Sequence alignment and location of positive selection sites in human formyl peptide receptors (FPRs): FPR1, FPR2 and mouse mFpr1. (A) Alignment of the protein sequence of human FPR1, FPR2 and mouse Fpr1. Positively selected amino acid sites [14] in three FPR isoforms are shown in color; (B) Schematic diagram for the location of the positive selection sites in the formyl peptide receptors, based on the sequence of human FPR1. The amino acids at these positions in each of the three receptors are marked on the right.
