c-Jun is a protein that in humans is encoded by the JUN gene. c-Jun in combination with c-Fos, forms the AP-1 early response transcription factor. It was first identified as the Fos-binding protein p39 and only later rediscovered as the product of the c-jun gene. It is activated through double phosphorylation by the JNK pathway but has also a phosphorylation-independent function. c-jun knockout is lethal, but transgenic animals with a mutated c-jun that cannot be phosphorylated (termed c-junAA) can survive.
