MeSH definition : A dystrophin-associated protein and component of the Biogenesis of Lysosomal Organelles
Complex-1 (BLOC-1 complex) which is essential for the formation of LYSOSOME - derived
organelles such as platelet dense granules and MELANOSOMES. DTNBP1 is expressed primarily
in the brain and neurons, where it functions with ADAPTOR PROTEIN COMPLEX 3 to transport
membrane proteins to NEURITES and nerve terminals. It also regulates the release of
neurotransmitters, transport of synaptic vesicles, and localization of DOPAMINE D2
RECEPTORS. Mutations in the DTNBP1 gene are associated with Type 7 HERMANSKY-PUDLAK
SYNDROME and SCHIZOPHRENIA.;
