MOCHA

Mocha is a naturally occuring mouse mutant with a null mutation in the delta subunit of AP-3 complex. In Mocha cells, the β3 amd μ3 subunits coassmeble into a heterodimer whereas the sigma 3 subunit remains monomeric. The mouse has a similar phenotype to the human genetic disorder, Hermansky Pudlak Syndrome (HPS). In both mice and humans, AP-3 deficiency results in hypopigmentation because of abnormalities in melanosomes. The Mocha cell line can be used to investigate the assembly of AP-3 complexes and AP-3 function.
