The color of hair, skin, and eyes in animals mainly depends on the quantity, quality, and
distribution of the pigment melanin, which occurs in two types: black to brown eumelanin …

Among the biopolymers, melanins are unique in many respects. The other essential
biopolymers–proteins, nucleic acids, and carbohydrates–are chemically well characterized; …

All melanin-colored ornaments contain a mixture of the two types of melanin, eumelanin and
pheomelanin. The reflectance spectrum of the ornament is, in part, a function of the ratio of …

The association between MSHR coding region variation and hair colour in humans has
been examined by genotyping 25 red haired and 62 non-red Caucasians, all of whom were …

The relationships between MC1R gene variants and red hair, skin reflectance, degree of
freckling and nevus count were investigated in 2331 adolescent twins, their sibs and parents …

Mammalian melanogenesis is regulated directly or indirectly by over 85 distinct loci.

Agouti protein and Agouti-related protein (Agrp) are paracrine-signaling molecules that
normally regulate pigmentation and body weight, respectively. These proteins antagonize …

Atomic force microscopy is used to investigate the structural organization of eumelanin

Most types of human oculocutaneous albinism (OCA) result from mutations in the gene for
tyrosinase (OCA1) or the P protein (OCA2), although other types of OCA have been …
