Cross-species summary: This locus, ASIP, encodes the agouti signalling protein, a peptide antagonist of the melanocyte-stimulating hormone receptor (MC1R), which is the product of the extension locus. As explained by Schneider et al. (PLoS Genet 10(2): e1004892; 2015), "The most common causes of melanism (black coat) mutations are gain-of-function alterations in MC1R, or loss-of function alterations in ASIP, which encodes Agouti signaling protein, a paracrine signaling molecule that inhibits MC1R signaling".

Species-specific description: Information relating to charcoal coat colour in Bengal cats (a cat breed originating from hybrid animals developed from crosses between the domestic cat (Felis silvestris catus) and the Asian leopard cat (Prionailurus bengalensis)) has been moved to 'OMIA:002549-9685 : Coat colour, charcoal, ASIP-related in Felis catus' [8/4/2022]

Molecular basis: Gershony et al. (2014): "The complete coding region of ASIP was directly sequenced in Asian leopard, domestic and Bengal cats. Twenty-seven variants were identified between domestic and leopard cats ... . The leopard cat ASIP haplotype was distinguished from domestic cat by four synonymous and four non-synonymous exonic SNPs, as well as 19 intronic variants, including a 42-bp deletion in intron 4."

Breed: Bengal (Cat) (VBO_0100040).
