What this target is
Its function as UniProt states it, where in a cell the protein is found, and which cell types and tissues transcribe its gene.
No single gene answers to Melatonin receptor type 1B. Names like this one are families or unsubtyped preparations — a measurement made against whatever receptors a tissue carried, before or without resolving which subtype bound the compound. A family has no one accession, and picking a member to stand for it would invent a precision the assay never had: asked for “Muscarinic acetylcholine receptor” UniProt returns CHRM1, and that answer is wrong.
Resolver said no gene lists this target name as a synonym — recorded by tools/fetch_expression.py, not written here.

Every measurement at this target
Each row links to the ChEMBL assay it came from.
Equilibrium binding constants 1
Ki and Kd — a concentration at equilibrium. Directly comparable across rows at the same target.
| Target | Class | Type | Value (nM) | pX | Organism | Assay |
|---|---|---|---|---|---|---|
| Melatonin receptor type 1B | Other named receptors | Ki | — no normalized value | — value does not convert to pX | Homo sapiens | CHEMBL3583714 |
Functional readouts 1
IC₅₀, EC₅₀, AC₅₀ and potency. Assay-dependent, and not interchangeable with a binding constant.
| Target | Class | Type | Value (nM) | pX | Organism | Assay |
|---|---|---|---|---|---|---|
| Melatonin receptor type 1B | Other named receptors | EC50 | — no normalized value | — value does not convert to pX | Homo sapiens | CHEMBL3583718 |
Other measurements 1
Everything else ChEMBL recorded for this compound — percentage inhibition, efficacy, half-life, cytotoxicity. Reported in the assay's own units, which is why no value is converted here.
| Target | Class | Type | Value (nM) | pX | Organism | Assay |
|---|---|---|---|---|---|---|
| Melatonin receptor type 1B | Other named receptors | Emax | — no normalized value | — value does not convert to pX | Homo sapiens | CHEMBL3583719 |
