How to interpret this panel
Phosphorylation, O-linked glycosylation, acetylation, ubiquitination and methylation entries identify candidate acceptor residues from sequence alone. N-linked glycosylation detects the canonical N-X-S/T sequon where X is not proline. Cysteines are shown as potential disulfide participants. These signals do not prove that a modification occurs in vivo; cellular localization, modifying enzymes, protein structure and experimental evidence are required.
