AP3B1

AP-3 complex subunit beta-1 is a protein that in humans is encoded by the "AP3B1" 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 Hermansky–Pudlak syndrome type 2.
Interactions.
AP3B1 has been shown to interact with AP3S2.
