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.

Species-specific description: "The Bengal cat breed consists of hybrid animals developed from crosses between the domestic cat (Felis silvestris catus) and the Asian leopard cat (Prionailurus bengalensis)" (Gershony et al., 2014)

Molecular basis: By sequencing a prime comparative candidate locus (ASIP) in Bengal cats, Asian leopard cats and domestic cats, Gershony et al. (2014) showed that the charcoal coat colouration/pattern in Bengal cats is strongly associated with heterozygosity for an ASIP haplotye from the euptilura form of Asian leopard cat (called A^Pbe) and the classic non-agouti alllele (a; see OMIA 000201-9685) from domestic cats. The A^Pbe allele, considered by Gershony et al. (2014) to be the wild-type ASIP allele in euptilura Asian leopard cats, differs from the non-agouti a allele as follows: c.41G>C; absence of c.123-124 2-bp del; c.142T>C; c.251A>G; and C.302 A>G.
