BLOC-1 subunit 4, also called Cappuccino homolog (CNO) is a protein that in humans is encoded by the BLOC1S4 gene. This protein is a subunit of BLOC-1 (biogenesis of lysosome-related organelles complex 1), which is involved in the biogenesis of certain organelles like melanosomes and dense granules.

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.

Interactions

BLOC1S4 has been shown to interact with BLOC1S2 and BLOC1S6.
