I · Identity
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.
Motilin receptor
Receptor for motilin
Quoted from UniProt’s FUNCTION annotation for O43193 (reviewed).
What it acts with
STRING’s highest-confidence human functional partners. The combined score mixes several kinds of evidence, so each channel is shown separately — a partner supported by experiment is a different claim from one supported only by text mining, and for a receptor this is where its coupling appears as evidence rather than as assertion.
Where it sits in the cell
- Plasma membrane
- Cytosol
Human Protein Atlas, by antibody immunofluorescence in cell lines — a different assay from the expression figures below, which are RNA.
UniProt, curated Cell membrane
Expression by cell type
Single cell type RNA, the 1 highest of those the Human Protein Atlas reports for this gene. Transcript, not protein, and a cell type rather than a tissue.
- Neutrophil progenitors1.8 nCPM
Expression by tissue
The tissues this gene is enriched in, by consensus RNA. A tissue absent from this list is one the Atlas does not call specific for this gene, which is not the same as absent from it.
- thyroid gland1.6 nTPM
- bone marrow1.2 nTPM
II · Anatomy
Where the gene is transcribed
The same two atlases the compound plates use, asked about this gene alone. Brain on the left, peripheral and autonomic tissues on the right.
Brain
basal ganglia: drawn as the caudate nucleus, putamen and globus pallidus.
Measured but not drawn — this anatomogram has no outline for them: retina 0.1.
Body
Square-root ramp · shared scale across both plates
Shading is transcript level — not affinity, and not affinity combined with expression. Outlined but unshaded organs hold none of MLNR transcript above the atlas’s detection threshold. Anatomy from EMBL-EBI Anatomogram (Apache License 2.0); regions identified by Uberon (uberon.org), CC BY 3.0.

Transcript is not protein. These are RNA levels for MLNR, shaded on √nTPM so that a three-order range stays legible — on a linear ramp every region but the strongest would read as blank, which looks like absence rather than less. A region carrying no shading is one the atlas reports no consensus value for, not one where the gene is silent. And a gene being transcribed somewhere is not evidence that any compound reaches it. Human Protein Atlas, RNA expression, nTPM (normalized transcripts per million), consensus tissue dataset.
