  4. 4. Signaling for color change in melanophores : and a biosensor application

    Author : Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
    Keywords : color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

    Abstract : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells.
