Agouti | Veterinary Genetics Laboratory - UC Davis
In domestic cats, a 2 bp deletion (c.123delCA) in the agouti signaling protein disrupts protein function. This mutation has an autosomal recessive mode of inheritance, thus when two copies are present, pigment switching is prevented from occurring.

A cat hair showing light and dark bands caused by alternating production of agouti-signaling protein and α-MSH. The agouti gene, the Agouti-signaling protein (ASIP) is responsible for variations in color in many species.

Agouti hair showing alternating bands along the shaft. The agouti factor determines the "background" of the tabby coat, which consists of hairs that are banded with dark eumelanin and lighter phaeomelanin along the length of the hair shaft.

2023年12月20日 · The agouti gene and coat color variation in cats demonstrate the intricate relationship between genotype, gene expression, and phenotype. Understanding the role of this gene provides insights into the fascinating diversity of coat colors observed in cats.
Agouti and Tabby | Sparrow's Garden
The Agouti Gene. The A locus, Agouti, is responsible for determining patterning in many different mammals. It does this by affecting whether black pigment or red pigment is made. In a tabby cat, the background color is created by these signals turning on and off, resulting in a hair with alternating bands of black and red pigment.
