Explore experimentally verified, literature-supported and rule-based predicted post-translational modification sites for human GPCRs — with topology context and interactive 3D mapping.
Map PTM sites directly onto AlphaFold structures, inspect residues, and move between molecular context and evidence.
A unified view of phosphorylation, N-glycosylation, palmitoylation and ubiquitination with consistent evidence tiers.
GPCR topology gates predictions by extracellular, transmembrane and intracellular regions to improve biological plausibility.
