C-jun-amino-terminal kinase-interacting protein 4 is an enzyme that in humans is encoded by the SPAG9 gene.Extracellular signals are transduced into cells through mitogen-activated protein kinases. The structural organization of these kinases into specific signaling domains is facilitated by scaffolding proteins involved in closely tethering different kinases so that successive phosphorylation events can occur.
