. Mutation in AP-3 delta in the mocha mouse links endosomal transport to storage deficiency in platelets, melanosomes, and synaptic vesicles.. Neuron 21: 111-122, 1998. PubMed: 9697856
The mh cell line was derived from primary fibroblasts taken from muscle of homozygous mocha (mh/mh) mice. As a result of the mocha mutation, the fibroblasts are deficient in the delta subunit of the adaptor-like protein complex, AP-3. The cell line can be used to investigate both the assembly of AP-3 complexes and AP-3 function, and may serve as a model for Hermansky-Pudlak syndrome (HPS), a platelet storage pool deficiency syndrome.
