Biological function summary
The JNK proteins are involved in controlling cellular events like proliferation differentiation and apoptosis. They act as part of the MAPK signaling complex and involve scaffolding proteins that help organize these signaling pathways. In the cellular context JNK proteins are activated in response to stress signals like UV irradiation inflammatory cytokines and growth factors. This activation leads to diverse cellular outcomes depending on the specific JNK isoform and cell type.
Pathways
The JNK proteins are important in the MAPK signaling pathways and play a role in the AP-1 transcription factor regulation. They interact with proteins such as MEK4 and MEK7 which are upstream kinases that activate JNK through phosphorylation. The JNK signaling arm is distinct from the ERK and p38 MAPK pathways each having specific roles in cellular response modulation.
