Phosphorylation sites in rat MAP1B identified by tandem mass spectrometry. The table shows the peptide sequences identified by tandem mass spectrometry and, in red, the phosphorylated amino acids. In peptides in which there are ambiguous sites, only one of the listed sites is phosphorylated but which one was not able to be determined. Amino acids in green were phosphorylated in the Baliff et al. (Baliff et al., 2004) data set from embryonic mouse brain
