Summary: Predicted to enable identical protein binding activity; melanocortin receptor binding activity; and signaling receptor regulator activity. Acts upstream of or within brown fat cell differentiation. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in endoplasmic reticulum and plasma membrane. Is expressed in several structures, including brain; exocrine system; olfactory epithelium; respiratory system; and urinary system. Used to study adrenal gland disease.

Selective Interactions of Mouse Melanocortin Receptor Accessory Proteins with Somatostatin Receptors.
Title: Selective Interactions of Mouse Melanocortin Receptor Accessory Proteins with Somatostatin Receptors.
Data (including data from studies in transgenic mice) suggest that Mrap plays critical role in (1) regulation of lipolysis in adipose tissue, (2) regulation of enzyme expression in adipose tissue, and (3) whole-body energy balance.
Title: Regulation of Lipolytic Response and Energy Balance by Melanocortin 2 Receptor Accessory Protein (MRAP) in Adipocytes.
These results suggest that PPARgamma is required for transcriptional activation of the MRAP gene during adipogenesis, which contributes to understanding of the molecular mechanism of lipolysis in adipocytes.
Title: Transcriptional activation of melanocortin 2 receptor accessory protein by PPARγ in adipocytes.
The receptor was co-expressed with a cartilaginous fish (Callorhinchus milii) MRAP2 cDNA.
Title: Functional expression of Squalus acanthias melanocortin-5 receptor in CHO cells: ligand selectivity and interaction with MRAP.
C-terminal tail of the MC(4) receptor with the corresponding regions from the MC(2) receptor resulted in MRAP-dependent signaling
Title: Use of chimeric melanocortin-2 and -4 receptors to identify regions responsible for ligand specificity and dependence on melanocortin 2 receptor accessory protein.
The results establish that MRAP forms stable complexes with two different melanocortin receptors, facilitating surface expression of MC2 receptor but disrupting dimerization and surface localization of MC5 receptor.
Title: Opposite effects of the melanocortin-2 (MC2) receptor accessory protein MRAP on MC2 and MC5 receptor dimerization and trafficking.
MRAP not only facilitates MC2 receptor trafficking but also allows properly localized receptor to bind ACTH and consequently signal.
Title: Regions of melanocortin 2 (MC2) receptor accessory protein necessary for dual topology and MC2 receptor trafficking and signaling.
The melanocortin 2 receptor accessory protein exists as a homodimer and is essential for the function of the melanocortin 2 receptor in the mouse y1 cell line.

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.
