Rearrangements of pterinosomes and cytoskeleton accompanying pigment dispersion in goldfish xanthophores.


The cytoskeleton of goldfish xanthophores contains an abundance of unique dense structures (400 nm in diameter) that are absent in goldfish nonpigment cells and are probably remnants of pterinosomes. No major difference in protein composition between xanthophores and nonpigment cells (without these structures) was found that could account for these… (More)
