1 The dependence of the binding constant, K(obs), on [NaCl] was shown to be strong for binding of the tandem SH2 domain of the Syk kinase (Syk-tSH2) to doubly phosphorylated peptides derived from immune-receptor tyrosine activation motifs (dpITAMs): the slopes of plots of log(K(obs)) versus log [NaCl], designated SK(obs), ranged from -2.6 +/- 0.1 to -3.1 +/- 0.2.
