  • FunctionRequired for MC2R expression in certain cell types, suggesting that it is involved in the processing, trafficking or function of MC2R. May be involved in the intracellular trafficking pathways in adipocyte cells.
  • Tissue specificityExpressed in adrenal cortex, testis, breast, thyroid, lymph node, ovary and fat. Expressed in adipose tissues.
  • Involvement in diseaseDefects in MRAP are the cause of glucocorticoid deficiency type 2 (GCCD2) [MIM:607398]; also known as familial glucocorticoid deficiency type 2 (FGD2). GCCD2 is an autosomal recessive disorder due to congenital insensitivity or resistance to adrenocorticotropin (ACTH). It is characterized by progressive primary adrenal insufficiency, without mineralocorticoid deficiency.
  • Cellular localizationCytoplasm > perinuclear region. Cytoplasm. Cell membrane. Endoplasmic reticulum. Concentrated at the perinuclear membrane region. Upon insulin stimulation, it is redistributed into spotty structures throughout the cytoplasm (By similarity). Localizes both to plasma membrane and endoplasmic reticulum.

  • ab103319 stained U-87 MG cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab103319 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
