Figure 8. Alignment of 15 SPAK RFx[V/I] motif interacting proteins.
A) Proteins with threonine or serine residues located at positions 5 or 6 in docking motif, thus constituting putative targets for basophilic kinases, are indicated in blue. B) Proteins which do not contain threonine or serine residues at positions 5 or 6 in their docking motif. Note that two motifs do have negatively charged residues located at position 5 or 6.
