Premium Phosphosite-Specific 7TM Antibodies

Phosphorylation of intracellular serine and threonine residues is the most important post translational modification of G protein-coupled receptors (GPCRs) also called heptahelical or seven transmembrane receptors (7TMR). After agonist exposure, these receptors acquire an active conformation, which is recognized by a family of highly specialized GPCR kinases (GRKs). Agonist-driven phosphorylation by GRKs regulates acute receptor desensitization, arrestin recruitment, internalization, post-activation signaling, long-term tolerance and drug addiction. Phosphosite-specific 7TM antibodies are designed to specifically detect agonist-activated GPCRs. In fact, recent work shows that ligand profiling using phosphosite-specific 7TM antibodies provides valuble information on ligand bias beyond that obtained with conventional ß-arrestin recruitment assays. Phosphosite-specific 7TM antibodies are novel tools for GPCR research that can be used to:

  • profile agonist properties of novel GPCR ligands
  • decipher the phosphorylation barcode of GPCRs
  • determine the spatial and temporal dynamics of receptor phosphorylation
  • identify relevant kinases and phosphatases for GPCR phosphorylation and dephosphoryation
