The human PAK1 construct used for these analyses did not have a correct sequence from residue 501 to the end (545). Therefore this last part of the molecule was not covered; this is reflected in Figure 2A in Mayhew et al. (2007) "Identification of phosphorylation sites in betaPIX and PAK1." J Cell Sci. 2007 Nov 15;120(Pt 22):3911-8.
