Multiple sequence alignment of the PDE11A1, PDE11A2, and PDE11A3 GAF
domains to GAF domains of other PDEs. The GAF domain boundaries were
determined by the Simple Modular Architecture Tool (smart).
For clarity of viewing, 35–95 nonhomologous amino acid residues from
the N-terminal and C-terminal ends of the sequences delineated by
smart have been omitted. Numbers in parentheses at the end
of each sequence indicate the number of amino acids omitted. Stars mark
the conserved sequence motif present in most GAF domains. PDE2, HSPDE2A
