An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. [5] [6] It is responsible for the distribution of melanin pigment in mammals.[7] [8] Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment). [9]
In a mice model, the mice fed on a BPA diet were more likely to have a yellow coat corresponding to their lower methylation state in the promoter regions of the retrotransposon upstream of the Agouti gene. The Agouti gene is responsible for determining whether an animal's coat will be banded (agouti) or solid (non-agouti).
The agouti gene in mice is largely responsible for determining coat colour. The wild-type allele produces a blend of yellow and black pigmentation in each hair of the mouse. This yellow and black blend may be referred to as 'agouti' in colour. [3] One of the mutant alleles of the agouti gene
Updated leptin–melanocortin model. The central melanocortin system is defined anatomically as a collection of central nervous system circuits which include: . Neurons that express hypothalamic neuropeptide Y and agouti gene-related protein or proopiomelanocortin (POMC) and that originate in the arcuate nucleus.
The above is an example of the “agouti” gene locus, whereby the insertion of a transposable element upstream to the Agouti gene is hypermethylated from the supplementation and causes a change in the mice's coat color. Diets containing higher carbohydrate and fat content attempt to mimic typical Western-style diets may also be used in ...
