Abstract
An interesting question in developmental biology is why mutations in genes with functions essential for the majority of cells produce diseases affecting only specific tissues. For example, pigment dilution disorders are often the consequence of mutations in conserved vesicular traffic genes. In Hermansky-Pudlak, Griscelli, and Chediak-Higashi pigment dilution syndromes, vesicular traffic mutations affect several organs with one characteristic in common: to carry out their functions they depend to a great extent on lysosome-related organelles (LROs), such as the melanosomes in melanocytes. Conserved multimeric complexes, present in most cell types, target proteins to lysosomes or selected LROs using transport vesicles. By studying these diseases or the model organisms that are defective in these processes, we have learned that every cell type possesses a unique way to regulate its vesicular traffic machinery and to assemble its multimeric complexes. This is accomplished by subunits from these multimeric complexes acting in a cell-specific manner. Here, we review several fish pigment dilution mutants that represent models for human vesicular traffic diseases.
