| comment | Note that this term and its child terms are intended for receptors that are directly coupled to a signal transduction pathway. This term should therefore not be used to annotate decoy receptors and other proteins that bind a signal but do not pass the signal on. This term can be used to annotate dependence receptors that transduce a signal when a ligand is withdrawn (in this case, signal withdrawal is considered to be the initiating signal), or receptors that signal at a basal level in the absence of a bound agonist. For receptors that mediate transport of a substance into the cell by receptor-mediated endocytosis, consider instead the term 'cargo receptor activity ; GO:0038024' and its children.
