When Interleukin-27 subunit beta (EBI3) was expressed in cells, it accumulated in the endoplasmic reticulum and associated with the molecular chaperone calnexin(CANX), indicating that subsequent processing and secretion might be dependent on association with a second subunit (Devergne et al.1996)
Interleukin-27 subunit alpha (IL27) coexpressed with EBI3 permitted secretion as a soluble complex (Pflanz et al. 2002)

This is a black box event because there is not reported evidene about the mechanism of the traslocation of the IL-27 heterodimer from the endoplasmic reticulum to the extracellular region.
