COG complex subunit 4 is present in high molecular weight complexes that govern membrane movement between the Golgi and ER. Cog4 dependent trafficking and secretion of ECM components are required for protrusion and extension of the epithelial projections of the inner ear. Loss-of-function COG4-mutant cells have impaired glycosylation and reduced COG4 protein levels.
