Scientific Background: MLK1 (MAP3K9) is a protein-serine/threonine kinase of the TKL group and MLK family. It links to MAP kinases and will mediate activation of MKK/JNK via MAP2K4/MKK4 and MAP2K7/MKK7. Phosphorylation of T304, S308 and T312 increases MLK1's phosphotransferase activity. A mild effect on threonine phosphorylation and a minor impairment of JNK signalling can occur with a T305A mutation. Homodimerization via the leucine zipper domains is required for autophosphorylation and subsequent activation. The MKK/JNK pathway is involved in mediating release of cytochrome c from the mitochondria and inducing cell death via apoptosis. The MKK/JNK signalling pathway regulates stress response via activator protein-1 (Jun) and GATA4 transcription factors. It also plays a role in mitochondrial death signalling pathway, including the release cytochrome c, leading to cell death via apoptosis. MLK1 may be an oncoprotein (OP). In non-small-cell lung cancers, a gain of function has been observed with MLK1 (MAP3K9), which results in downstream activation of ERK1 and ERK2 MAP kinases.
