Descriptions

(Annotation based on sequence homology with Q16584)
Mixed lineage kinase 3 (MLK3) is a mitogen-activated protein kinase kinase kinase (MAPKKK) that activates the c-Jun N-terminal kinase (JNK) pathway through the dual phosphorylation of mitogen-activated protein kinase kinases 4/7 (MKK4/7). The catalytic domain of MLK3 is flanked by an N-terminal SH3 domain and a centrally located zipper and Cdc42/Rac-interactive binding (CRIB) motif. Zipper-mediated homo-oligomerization is required for full activity of MLK3, proper substrate phosphorylation, and activation of the JNK pathway. MLK3 is autoinhibited through an interaction between its SH3 domain and a proline-containing sequence between the zipper and the CRIB motif. Activated forms of the small GTPases Cdc42 and Rac interact with MLK3 in a CRIB motif-dependent manner to increase the autophosphorylation of MLK3 and substrate phosphorylation activity and to potentiate MLK3-induced activation of JNK. Activated Cdc42 translocates MLK3 to membranes and induces activation loop phosphorylation of MLK3.
