Fig. 2From: Molecular identification and functional characterization of IRF4 from common carp (Cyprinus carpio. L) in immune response: a negative regulator in the IFN and NF-κB signalling pathwaysPhylogenetic analysis of IRF4 protein sequences from different species. The phylogenetic tree was produced by the neighbour-joining method in MEGA 5.0. The red frame shows the common carp IRF4Back to article page
