proteins are intracellular proteins‚ or protein fractions‚ that have a high specific affinity for binding a known stimulus to cellular activity. Receptor proteins may be located at cell surfaces or within the interior of cells. They may detect hormones or instead keep track of what otherwise is going on in cell ’s environment. They may be enzymes or serve to relay the occurrence of signal reception in other ways such as by opening up ion channels. Receptor proteins are often targets for drug
