NCIt definition : Typically associated with the cell membrane, Protein Hormone Receptors selectively
bind with high affinity to genetically-encoded polymerized amino acids in peptide
linkage that have regulatory effects on the activity of specific target cells. A ligand-induced
conformational and functional change in the receptor alters its interaction with target
molecules, leading to changes in cellular physiology through modification of the activity
of signal transduction pathways.;
