| T1 |
0-78 |
Sentence |
denotes |
Identification and characterization of a novel MAP kinase kinase kinase, MLTK. |
| T2 |
79-212 |
Sentence |
denotes |
The MAPK cascades regulate a wide variety of cellular functions, including cell proliferation, differentiation, and stress responses. |
| T3 |
213-416 |
Sentence |
denotes |
Here we have identified a novel MAP kinase kinase kinase (MAPKKK), termed MLTK (for MLK-like mitogen-activated protein triple kinase), whose expression is increased by activation of the ERK/MAPK pathway. |
| T4 |
417-491 |
Sentence |
denotes |
There are two alternatively spliced forms of MLTK, MLTKalpha and MLTKbeta. |
| T5 |
492-612 |
Sentence |
denotes |
When overexpressed in cells, both MLTKalpha and MLTKbeta are able to activate the ERK, JNK/SAPK, p38, and ERK5 pathways. |
| T6 |
613-746 |
Sentence |
denotes |
Moreover, both MLTKalpha and MLTKbeta are activated in response to osmotic shock with hyperosmolar media through autophosphorylation. |
| T7 |
747-905 |
Sentence |
denotes |
Remarkably, expression of MLTKalpha, but not MLTKbeta, in Swiss 3T3 cells results in the disruption of actin stress fibers and dramatic morphological changes. |
| T8 |
906-969 |
Sentence |
denotes |
A kinase-dead form of MLTKalpha does not cause these phenomena. |
| T9 |
970-1089 |
Sentence |
denotes |
Inhibition of the p38 pathway significantly blocks MLTKalpha-induced stress fiber disruption and morphological changes. |
| T10 |
1090-1212 |
Sentence |
denotes |
These results suggest that MLTK is a stress-activated MAPKKK that may be involved in the regulation of actin organization. |
