Identification of in vitro phosphorylated sites by mass spectrometry ^aReynolds, et al. study [37] ^bConnell, et al. study [38] ^cIdentification of in vitro phosphorylated sites by phosphorylation site-specific antibodies. Antibodies were unavailable for those sites marked with an asterisk. S422, not identified by either mass spectrometry or antibody analysis, was a negative control.
