signaling receptor
Let an agent explain signalling receptors and their classes, relay mechanisms of signal transduction, describe roles in physiology, disease and drug action, and distinguish signalling receptors from transporters and sensory receptor cells.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain signalling receptors and their classes, relay mechanisms of signal transduction, describe roles in physiology, disease and drug action, and distinguish signalling receptors from transporters and sensory receptor cells.
A protein that binds a signalling molecule such as a hormone, cytokine, growth factor or neurotransmitter and initiates a cellular response, including cell surface receptors such as cytokine receptors, tumour necrosis factor receptors, the erythropoietin receptor and receptors exploited by toxins such as the anthrax toxin receptor, and intracellular receptors for lipophilic signals; signalling receptors are central to physiology and are major drug targets.
What it is for: Receiving signals and triggering cellular responses.
It can be explain classes and mechanisms; relay roles in physiology and disease; describe drug targeting; distinguish from related proteins and cells.

Not visible; proteins shown as structural models spanning membranes or in the cytoplasm.
How it is recognised
Protein binding a signal and starting a response
Cell surface and intracellular classes

- How should nomenclature databases be linked?
- The registry entry has merged aliases naming specific receptors; should they be split off?
