Guanosine Triphosphate 33-36 mitogen-activated protein kinase kinase kinase 11 Homo sapiens 59-63 9003778-2 1996 Cdc42 and the related small GTP binding protein Rac1 can activate the SAPK/JNK and p38/RK stress-responsive kinase cascades, suggesting that MLK-3 may have a role in upstream regulation of these pathways. Guanosine Triphosphate 28-31 mitogen-activated protein kinase kinase kinase 11 Homo sapiens 141-146 9427749-4 1998 Using yeast two-hybrid analysis and in vitro dot-blots, we show that MLK2 and MLK3 interact with the activated (GTP-bound) forms of Rac and Cdc42, with a slight preference for Rac. Guanosine Triphosphate 112-115 mitogen-activated protein kinase kinase kinase 11 Homo sapiens 78-82 8910292-10 1996 Furthermore, we present evidence that MLK3 binds the GTP-binding proteins Cdc42 and Rac1 in vivo and that MLK3 mediates activation of MEKK-SEK-JNK kinase cascade by Rac1 and Cdc42.
