Figure 1.

A comparison of selected Fc receptors between humans and rhesus macaque species. Differences in protein coding sequences reflects insertions, deletions, and sites of polymorphism.

(1) The number of N glycan motifs is conserved across rhesus and cynomolgus macaques.

(2) The ranges of values represent the minimum and maximum changes involved in shifting from human to rhesus; exact numbers depend on the allelic variants being compared.

(3) Rhesus macaque FcγRI is truncated by 17 amino acids at its C terminus relative to the human variant.
