AP3B1

AP-3 complex subunit beta-1 is a is_associated_with::protein that in humans is encoded by the AP3B1 is_associated_with::gene.

Function
This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. The encoded protein is part of the heterotetrameric AP-3 protein complex which interacts with the scaffolding protein clathrin. Mutations in this gene are associated with is_associated_with::Hermansky-Pudlak syndrome type 2.

Interactions
AP3B1 has been shown to interact with is_associated_with::AP3S2.
