Interleukin 27 subunit alpha (IL27, IL-27p28) binds Interleukin 27 subunit beta (EBI3) forming the Interleukin 27 heterodimeric complex (IL27:EBI3). When expressed alone, human EBI3 is associated with the endoplasmic reticulum (ER) resident molecular chaperone calnexin (CANX) and is retained in the ER (Devergne et al. 1997). Co expression of IL27 and EBI3 enables formation of IL27:EBI3, allowing secretion (Pflanz et al. 2002).
This is a Black Box event because there is not reported which reaction occurs first: the association of IL27 to EBI3:CANX and later the Interleukin 27 heterodimeric protein formation or first the dissociation of EBI3 from CANX and later formation of the Interleukin 27 heterodimeric protein formation.
