The PHD motif of Map3k1 activates cytokine-dependent MAPK signaling
نویسندگان
چکیده
We generated a mutation in the gene encoding mitogen-activated protein kinase kinase kinase 1 (Map3k1) that results in a protein with an inactive plant homeodomain (PHD). Map3k1(mPHD) cells are defective in cytokine-mediated MAPK signaling. Protein array identified transforming growth factor (TGF-β)-activated kinase 1 binding protein 1 (Tab1) as a PHD substrate. The Map3k1 PHD transfers Lys63-linked poly-ubiquitin onto Tab1 to activate MAPKs.

The MEKK1 PHD ubiquitinates TAB1 to activate MAPKs in response to cytokines
Unlike the other MAP3Ks, MEKK1 (encoded by Map3k1) contains a PHD motif. To understand the role of this motif, we have created a knockin mutant of mouse Map3k1 (Map3k1(m) (PHD)) with an inactive PHD motif. Map3k1(m) (PHD) ES cells demonstrate that the MEKK1 PHD controls p38 and JNK activation during TGF-β, EGF and microtubule disruption signalling, but does not affect MAPK responses to hyperosm...

Considering that MAPK (mitogen- activated protein kinase) signaling pathway has an important role in the progression of inflammatory cytokine secretion in type 2 diabetes mellitus (T2DM), we have recently investigated the reported genetic polymorphism from genome wide association study in MAP3K1 (mitogen-activated protein kinase kinase kinase 1) in diabetes as an important member of MAPK signal...

MAPK signaling is important for T lymphocyte development, homeostasis, and effector responses. To better understand the role of Mekk1 (encoded by Map3k1) in T cells, we conditionally deleted Map3k1 in Lck(Cre/+)Map3k1(f/f) mice, and these display larger iNKT cell populations within the liver, spleen, and bone marrow. Mekk1 signaling controls splenic and liver iNKT cell expansion in response to ...
