Fig. 1. Amino acid alignment of trout tMEK, deduced from the determined complete
coding region of the nucleotide sequence, and carp cMEK1 isoform (GenBank
accession no. AB063390), human hMAP2K2 (BC018645), rat rMAP2K2 (NM_205388),
and carp cMKK4 (AB063389). Specific protein interaction sites indicated are:
putative MAPK docking site (amino acids 127; underlined), NES-sequence
(AA 3647, boxed), and catalytic domain (AA 70364, grey
background); amino acid numbering refers to trout MEK.
