- Sample size (n) considered for each analysis is shown. Sites identified as positively selected by at least two ML analyses are underlined. Codons are given with a posterior probability ≥ 90 % in the Bayes Empirical Bayes (BEB) analysis for PAML M8; p-values < 0.1 for SLAC, FEL, IFEL and MEME; Bayes Factor > 50 for REL. †indicates PSS found only in a specific region for each species. Validated PSS also found with human antigen-binding sites (ABS) are shadowed
