Receptors are proteins or protein complexes that bind specific signaling molecules, known as ligands, to initiate
Ionotropic (channel) receptors form or regulate ion channels that open in response to ligand binding. Binding
Metabotropic receptors are G‑protein‑coupled receptors (GPCRs) and other receptors that engage secondary messenger systems rather than
Enzyme‑linked receptors possess intrinsic or associated enzymatic activity. The epidermal growth factor receptor (EGFR) is a
Nuclear hormone receptors reside predominantly in the cytoplasm or nucleus and bind lipophilic ligands such as
In many cases, receptor families overlap or interact. For instance, membrane GPCRs can modulate ion channel
