Structural and mutagenesis studies revealed how CRF is recognized by its GPCR receptor CRFR1 through a two-step binding model, identifying specific residues critical for both binding and receptor activation.
Key findingCRF-CRFR1 molecular recognition involves a two-step binding model: C-terminal CRF helix binds the receptor N-terminus (affinity), then N-terminal CRF
What the researchers found
CRF-CRFR1 molecular recognition involves a two-step binding model: C-terminal CRF helix binds the receptor N-terminus (affinity), then N-terminal CRF contacts the receptor core (activation) — structural basis for designing CRF receptor-selective drugs.
