For Research Use Only. Not for use in diagnostic or therapeutic procedures.
Component of a protein kinase signal transduction cascade. Activates the CSBP2, P38 and JNK MAPK pathways, but not the ERK pathway. Specifically phosphorylates and activates MAP2K4 and MAP2K6.

CIN85 binding to a C-terminal motif within hTTP leads to the increased phosphorylation of hTTP, possibly through enhanced association with MEKK4 PMID: 20221403
MEKK4 is the MAPK kinase kinase for TRAF4 regulation of the JNK pathway PMID: 16157600
Taken together, these results indicate a novel role for CIN85 in the regulation of cellular stress response via the MAPK pathways. PMID: 16256071
In this review, the role of MKK4 in cancer development appears complex, as some studies support a pro-oncogenic role for MKK4, while others suggest it may have tumor suppressor functions. PMID: 17496914
