Il12a:Il12b translocates from Golgi lumen to late endosome lumen
Interleukin-12 (Il12) translocates from the Golgi to the late endosome.

Il12 has been localized intracellularly in late endocytic vesicles marked by the soluble N-ethylmaleimide-sensitive factor accesory protein receptor (SNARE) termed Vesicle-associated membrane protein 7 (Vamp7).
Immunoelectron microscopy on cells expressing p35-SV5 (recombinant murine Il12a with simian virus 5) revealed that the majority of Il12a was associated with Golgi stacks and nearby tubovesicular membranes representing the trans-Golgi Network (Chiaruttini et al. 2016). A fraction of the protein was contained in vesicles and tubules associated with late-endosomes/lysosomes. This indicates that post-golgi trafficking of bioactive Interleukin-12 heterodimer in dendritic cells utilizes late endocytic vesicles preferentially marked by Vamp7.
