Sequence identity between the human and mouse FPRs Shown in the table are percent of identical amino acids between the receptors, based on pairwise comparison of the entire sequence of each receptor using the ALIGN program (Scientific & Educational Software, ver. 1.02). The FPR1–98 sequence (Boulay et al. 1990a) is used for the comparison. Note that the gene product of Fpr-rs5 used in sequence comparison is 246 amino acids. The size of each receptor is indicated in the first column
