Identification of PKA-phosphorylated residues in HCN4 GST fusion proteins. Compiled peptide sequences from tandem MS analysis of the HCN4 portions of the GST fusion proteins. Bold underlined residues were identified by MS sequencing; plain text residues were not resolved by MS. Red highlighting indicates residues found to be phosphorylated in multiple peptide fragments, and green highlighting indicates residues found to be phosphorylated in single peptide fragments.
