Agouti

Molecular biology A gene expressed during the hair-growth cycle in the neonatal skin of mice, in which it is a paracrine regulator of pigmentation. The secreted agouti protein antagonises binding of alpha-melanocyte-stimulating hormone to its receptor (melanocortin 1 receptor) on the surface of hair bulb melanocytes, altering intracellular cAMP levels. Because of its role in regulating coat colour, agouti has served as a model of gene action and interaction.
Zoology A popular term for any of the guinea pig-like rodents of the genus Dasyprocta, which are native to the Western Hemisphere.

agouti

a fur coloration in which there are alternating light and dark bands of colour on the individual hairs, giving a speckled brownish appearance. Such a fur coloration is found in mammals such as rabbits, rats and mice.
