Plant-specific IRAK pseudokinase families. (A) Phylogenetic tree of catalytically active and pseudokinase members of the IRAK family. The 9 plant IRAK pseudokinase families are labeled, and IRAK pseudokinase sequences are shown in red. Canonical IRAK sequences are shown in gray. Outgroup sequences are shown in black. (B) Sequence logos of catalytic motifs for IRAK pseudokinase families. (C) Unique domain structures observed in plant IRAK pseudokinase families. The most common domain structures observed in each family are shown (occurring >5%), with frequencies of each domain structure indicated.
