agouti
Central American rodent that has given its name to a grey flecked coat coloration in mice caused by alternate light and dark bands on individual hairs. The gene codes for a 131 residue secreted protein that regulates phaeomelanin synthesis in melanocytes but associated with the locus are genes important in embryonic development. Mice with dominant mutation at the Ay locus develop diabetes and obesity. The agouti gene product binds to melanocortin receptor 1 but does not antagonise a -MSH and has similar antiproliferative effects on melanoma cells in culture. The dark agouti (DA) rat has a high susceptibility to developing arthritis.
