Agouti is linked to the wideband gene, with about a 30% crossover rate. [33] Like white bellied agouti mice, rabbits with wildtype agouti produce transcripts with different untranslated 5' ends that have different dorsal and ventral expression. The 1A exon is only expressed in the belly region and may be responsible for the lighter color there. [3]
In 2003, Jirtle provided molecular evidence that maternal dietary supplementation of Agouti viable yellow (A vy) mice with methyl donors (i.e. folic acid, choline, vitamin B 12, and betaine) altered the coat color distribution and disease susceptibility in genetically identical offspring by increasing DNA methylation at the A vy locus.
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]
Punnett square for the agouti gene in mice, demonstrating a recessive lethal allele. [2] Lethal alleles were first discovered by Lucien Cuénot in 1905 while studying the inheritance of coat colour in mice. The agouti gene in mice is largely responsible for determining coat colour. The wild-type allele produces a blend of yellow and black ...

Mouse Genome Informatics (MGI) is a free, online database and bioinformatics resource hosted by The Jackson Laboratory, with funding by the National Human Genome Research Institute (NHGRI), the National Cancer Institute (NCI), and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

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 ...
Gene targeting was developed in mammalian cells in the 1980s, [24] [25] [26] with diverse applications possible as a result of being able to make specific sequence changes at a target genomic site, such as the study of gene function or human disease, particularly in mice models. [27] Indeed, gene targeting has been widely used to study human ...
