Protein cappuccino homolog is a protein that in humans is encoded by the CNO gene.^[1][2][3]

This intronless gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. A similar protein in mouse is a component of a protein complex termed biogenesis of lysosome-related organelles complex 1 (BLOC-1), and is a model for Hermansky-Pudlak syndrome. The encoded protein may play a role in intracellular vesicular trafficking.^[3]

Interactions

CNO (gene) has been shown to interact with BLOC1S2^[4] and PLDN.^[4]
