Molecular cloning and expression of the human melanocyte stimulating hormone receptor cDNA

Chhajlani, Vijay, Wikberg, Jarl E.S.·1992·FEBS Letters

Abstract

Melanocytes and melanoma cells are known to possess receptors for melanocyte stimulating hormone (MSH). A cDNA clone, designated IID, has been isolated from human melanoma cells and encodes a MSH receptor. The cloned cDNA encodes a 317 amino acid protein with transmembrane topography characteristics of a G‐protein‐coupled receptor, but it does not show striking similarity to already published sequences of other G‐protein‐coupled receptors. When IID cDNA is expressed in COS‐7 cells, it binds an 125 I‐labelled MSH analogue (NDP‐MSH) in a specific manner. The bound ligand could be displaced by melanotropic peptides, α‐MSH, β‐MSH, γ‐MSH and ACTH (adrenocorticotropic hormone), but not by the non‐melanotropic peptide, β‐endorphine. This is the first report of the cloning of a receptor gene of the melanotropin receptor family.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
