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]
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]
Thomas Johnson later showed that life extension of up to 65% was due to the mutation itself rather than due to calorie restriction, [2] and he named the gene age-1 in the expectation that other genes that control aging would be found. The age-1 gene encodes the catalytic subunit of class-I phosphatidylinositol 3-kinase (PI3K).

According to the U.S. Centers for Disease Control and Prevention, while "any vaccine can cause side effects", [11] most side effects are minor, primarily including sore arms or a mild fever. [11] Unlike most medical interventions vaccines are given to healthy people, where the risk of side effects is not as easily outweighed by the benefit of ...

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 ...
