Population Differences in the Frequency of the Agouti Signaling Protein g.8818A>G Polymorphism
Pigment Cell Research, 2004The role of agouti signaling protein (ASIP) in human pigmentation pathways is not definitively understood although its murine homologue regulates, in part, pheomelanogenesis. We have reported an association of a polymorphism in the 3′‐untranslated region of ASIP (g.8818A>G) with dark hair and eye color among a group of European‐Americans (Am J Hum ...

Hair and feather pigmentation is mainly determined by the distribution of two kinds of melanin, eumelanin and pheomelanin, which produce brown to black and yellow to red colorations, respectively. The agouti signaling protein (ASIP) acts as an antagonist or an inverse agonist of the melanocortin 1 receptor (MC1R), a G protein-coupled receptor for α ...

Enterostatin, a gut-brain peptide, inhibits dietary fat intake in rats. The purpose of this study was to identify the intracellular signaling pathways that are responsive to enterostatin and that modulate the effects of enterostatin on the expression of Agouti-related protein (AgRP).

Brilliant plumage is typical of male birds, thus sexual plumage dichromatism is seen in many avian species; however, the molecular mechanism underlying this remains unclear. The agouti signaling protein (ASIP) is a paracrine factor that stimulates yellow/red pigment (pheomelanin) synthesis and inhibits black/brown pigment (eumelanin) synthesis in ...

Important regulatory controls of melanogenesis that operate at the subcellular level to modulate the structural and/or the functional nature of the melanins and melanin granules produced in melanocytes are reviewed. Melanocyte stimulating hormone and agouti signal protein have antagonistic roles and possibly opposing mechanisms of action in the ...

Agouti signalling protein (ASIP) is an endogenous antagonist of melanocortin-1 receptor (MC1R) and is involved in the regulation of pigmentation in mammals. The objective of this study was to identify and characterise the ASIP gene in domestic goose.

A polymorphism in the agouti signalling protein (ASIP) is associated with decreased levels of mRNA
Pigment Cell Research, 2006SummaryTo date, a role for agouti signalling protein (ASIP) in human pigmentation has not been well characterized. It is known that agouti plays a pivotal role in the pigment switch from the dark eumelanin to the light pheomelanin in the mouse. However, because humans do not have an agouti banded hair pattern, its role in human pigmentation has been ...

Bovine embryos produced in vitro are developmentally inferior compared to in vivo derived embryos due to the lack of optimization of the oocyte and embryo culture conditions in vitro. Agouti-signaling protein (ASIP), a secreted protein produced by the bovine oocyte, has been recently shown to aid in acquiring oocyte developmental competence. Therefore,
