Jun N-terminal kinase 1 (JNK1)

Target: JNK1
Molecular classification: Mitogen-activated protein kinases (MAPKs), c-Jun N-terminal kinases subfamily, Enzyme, Protein Kinase

Overview

Jun N-terminal kinase 1 (JNK1), also known as mitogen-activated protein kinase 8 (MAPK8), is a member of the c-Jun N-terminal kinases, which are part of the mitogen-activated protein kinase (MAPK) family. JNK1 plays a central role in transducing extracellular stress signals into intracellular responses and is involved in regulating various cellular processes including cell growth, differentiation, survival, apoptosis, neurodegeneration, inflammation, and cytokine production.

Other names: MAPK8JNKMitogen-activated protein kinase 8

Mechanism of action

Kinase inhibition, modulation of downstream transcription factors (e.g., AP-1)
