receptorai
Receptorai, often called receptors in English, are cellular proteins that detect chemical signals and initiate a response in the cell. In Lithuanian usage, receptoriai refers to these proteins. Receptors bind ligands with high specificity and affinity, and the binding event triggers changes in the receptor’s activity that propagate signals inside the cell.
Location and types: Many receptors reside on the cell surface, where they interact with extracellular ligands.
Mechanism: ligand binding induces conformational changes that activate downstream pathways. Surface receptors commonly use second messengers
Physiology and pharmacology: Receptors orchestrate virtually all physiological processes and are frequent drug targets. Ligands can
Examples and relevance: Notable receptors include the insulin receptor, beta-adrenergic receptors, nicotinic acetylcholine receptors, and NMDA
