Summary: Enables melanocortin receptor activity and peptide hormone binding activity. Involved in several processes, including adenylate cyclase-modulating G protein-coupled receptor signaling pathway; homoiothermy; and sodium ion homeostasis. Predicted to be active in cytoplasm and plasma membrane. Human ortholog(s) of this gene implicated in obesity. Orthologous to human MC3R (melanocortin 3 receptor).

The increase in hypothalamic nesfatin-1 participates in regulating feeding behavior through the MC3/4R-ERK signaling especially after SG and RYGB.
Title: Hypothalamic nesfatin-1 mediates feeding behavior via MC3/4R-ERK signaling pathway after weight loss in obese Sprague-Dawley rats.
MC3R deficiency caused a reduction of food intake and body weight, whereas at the same time exhibited additive effects on top of MC4R deficiency on lipid and glucose metabolism.
Title: Effects of Melanocortin 3 and 4 Receptor Deficiency on Energy Homeostasis in Rats.
Study demonstrates an arcuate nucleus of the hypothalamus pro-opiomelanocortinergic projection onto ventral tegmental area dopaminergic neurons that modulates motivation for palatable food via activation of melanocortin 3 receptor signaling.
Title: Melanocortin 3 Receptor Signaling in Midbrain Dopamine Neurons Increases the Motivation for Food Reward.
in rats immunized with M4R and M3R peptides the sensitivity of ACSS thyrocytes to TSH were decreased, whereas in rats iimunized with 5-HT1BR peptide the deficit of thyroid hormones was associated with decreased level of TSH
Title: [THE THYROID STATUS OF RATS IMMUNIZED WITH PEPTIDES DERIVED FROM THE EXTRACELLULAR REGIONS OF THE TYPES 3 AND 4 MELANOCORTIN RECEPTORS AND THE 1B-SUBTYPE 5-HYDROXYTRYPTAMINE RECEPTOR].
We showed that the melanocortin-3/4 receptor antagonist SHU 9119 attenuates the food intake-suppressive effect of aminoprocalcitonin.
Title: Aminoprocalcitonin-mediated suppression of feeding involves the hypothalamic melanocortin system.
Results indicate that activation of MC3/4Rs in the paraventricular nucleus increases the sympathetic outflow and blood pressure via the cAMP-protein kinase A pathway.
Title: Melanocortin 3/4 receptors in paraventricular nucleus modulate sympathetic outflow and blood pressure.
Compared with low-activity rats, high-activity rats show enhanced mRNA expression of MCRs in the brain, specifically of MC3R in the paraventricular nucleus.
Title: Region-specific differences in brain melanocortin receptors in rats of the lean phenotype.
These results show that immunization against the melanocortin-3 receptor resulted in the production of Abs with positive or negative allosteric properties.
Title: Antibodies raised against different extracellular loops of the melanocortin-3 receptor affect energy balance and autonomic function in rats.
Data are consistent with the view that energetic and feeding responses are not controlled by regionally divergent MC3/4Rs and can be elicited from multiple, anatomically distributed MC3/4R populations.
Title: Hypothalamic and hindbrain melanocortin receptors contribute to the feeding, thermogenic, and cardiovascular action of melanocortins.
Efforts revealed a sequence consistent with that predicted by the rat genome, but different from the published receptor by three amino acids, all of which were located in the predicted second transmembrane domain.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
