Peptide Receptor Affinity

Meaning

Peptide receptor affinity is the quantitative measure of the strength and duration of the binding interaction between a specific signaling peptide and its cognate cell surface receptor. This affinity dictates the biological potency of the peptide, as a higher affinity means the peptide can elicit a maximum cellular response at a lower concentration. Clinically, understanding this parameter is crucial for predicting the efficacy and determining the precise therapeutic dosage of peptide-based interventions.
