A Gene expansion in the Amazon sailfin catfish enriched in immune system-related functional categories. B Structure of immunoglobulins and the mechanism by which the Ig V-set domain recognizes different antigens. C Specific tandem expansion of Ig V-set domains on chromosome 10 of the Amazon sailfin catfish, with a comparison of nearby genes in other catfish species. D Specific tandem expansion of Ig V-set domains on chromosome 1 of the Amazon sailfin catfish, and comparison with nearby genes in other catfish species. E Specific tandem expansion of the CD300 gene cluster on chromosome 8 of the Amazon sailfin catfish, with a comparison of neighboring genes in other catfish species.
