Figure 4.
Sequence alignment of human IFNAR2 (A), IL10R2 (B), and IFNAR1 (C) to their chicken counterparts. Long overlines indicate leader peptides and transmembrane domains; short overlines represent links between SD100 domains. In the IFNAR1 alignment, (###) indicating the link between the two D200s highlights the duplication of the external domain. Identical (*), similar (:), and related (.) residues are indicated. Respective percents of identity for IFNAR2, IL10R2, and IFNAR1 are 28%, 42%, and 36%.
