Cell surface receptor

<p>Cell surface receptors (membrane receptors, transmembrane receptors) are <a href="/facts/Receptor_(biochemistry)/tjTAC76a">receptors</a> that are embedded in the <a href="/facts/Cell_membrane/vAXSD0DT">plasma membrane</a> of <a href="/facts/Cell_(biology)/bLM9UQvy">cells</a>. They act in <a href="/facts/Cell_signaling/6oYAVP9I">cell signaling</a> by receiving (binding to) <a href="/facts/Extracellular_matrix/kaHC5Ez8">extracellular molecules</a>. They are specialized <a href="/facts/Integral_membrane_protein/Vztpmlu1">integral membrane proteins</a> that allow communication between the cell and the <a href="/facts/Extracellular/UEPUhSN8">extracellular space</a>. The extracellular molecules may be <a href="/facts/Hormone/WFnBnINJ">hormones</a>, <a href="/facts/Neurotransmitter/LlpYFSU3">neurotransmitters</a>, <a href="/facts/Cytokine/SdWpWABH">cytokines</a>, <a href="/facts/Growth_factor/D1xnRbcH">growth factors</a>, <a href="/facts/Cell_adhesion_molecule/84EkpbAb">cell adhesion molecules</a>, or <a href="/facts/Nutrient/34bn4skK">nutrients</a>; they react with the receptor to induce changes in the <a href="/facts/Metabolism/WxDrm8k5">metabolism</a> and activity of a cell. In the process of <a href="/facts/Signal_transduction/1bs0Me6w">signal transduction</a>, <a href="/facts/Ligand_(biochemistry)/44QLL4eU">ligand binding</a> affects a <a href="/facts/Biochemical_cascade/bCsA7XXG">cascading chemical change</a> through the cell membrane.
