Activation loop phosphorylation of ERK3/ERK4 by group I p21 (show CDKN1A Antibodies)-activated kinases (PAKs) defines a novel PAK-ERK3/4-MAPK-activated protein kinase 5 (show MAPKAPK5 Antibodies) signaling pathway.
Data defined a novel MK5 (show MAPKAPK5 Antibodies) interaction motif (FRIEDE) within both ERK4 and ERK3 that is essential for binding to the C-terminal region of MK5 (show MAPKAPK5 Antibodies).
Data show that in contrast to ERK3, ERK4 (MAPK4) is a stable protein and binds to MAPKAPK-5 (show MAPKAPK5 Antibodies). Interaction of ERK4 with MAPKAPK-5 (show MAPKAPK5 Antibodies) leads to translocation of MAPKAPK-5 (show MAPKAPK5 Antibodies) to the cytoplasm and to its activation by phosphorylation. ERK4 can form dimers with ERK3.
Results uncover a unique role for ERK3 (show RYK Antibodies), dependent on its kinase activity, during T cell development and show that this atypical MAPK (show MAPK1 Antibodies) is essential to sustain CD4 (show CD4 Antibodies)(+) CD8 (show CD8A Antibodies)(+) (DP) thymocytes survival during RAG-mediated rearrangements.
The atypical MAPK (show MAPK1 Antibodies) ERK3 (show RYK Antibodies) is a new and important regulator of T cell receptor-induced T cell activation.
Data suggest that ERK3 (show RYK Antibodies) is crucial for spindle stability and required for the metaphase-anaphase transition in mouse oocyte maturation.
Data suggest that Erk4 is dispensable for mouse embryonic development and reveals that Erk3 (show RYK Antibodies) and Erk4 have acquired specialized functions through evolutionary diversification.
ERK3 (show RYK Antibodies) biological activity is regulated by its cellular abundance through the control of protein stability
Data show that extracellular-regulated kinase 3 (ERK3 (show RYK Antibodies)) specifically interacts with the MAPK-activated protein kinase 5 (MK5 (show MAPKAPK5 Antibodies) or PRAK (show MAPKAPK5 Antibodies)) in vitro and in vivo.
Results demonstrate a specific interaction between extracellular signal-regulated kinase 3 (ERK3 (show MAPK6 Antibodies)) and mitogen-activated protein kinase-activated protein kinase-5 (MK5 (show MAPKAPK5 Antibodies)).
p38gamma (show MAPK12 Antibodies) MAP kinase (show MAPK1 Antibodies) (SAPK3/p38gamma (show MAPK12 Antibodies)) was shown to catalyse phosphorylation of SAP97 (show DLG1 Antibodies).
Results show that Cdo (show CDO1 Antibodies) is important for full Abl kinase activity, and Abl (show ABL1 Antibodies) is necessary for full activation of p38 MAPK (show MAPK14 Antibodies), during myogenic differentiation.
a critical role for Erk3 (show RYK Antibodies) in the establishment of fetal growth potential and pulmonary function in the mouse
Data show that MPK4 phosphorylation of MYB75 increases its stability and is essential for light-induced anthocyanin accumulation. Our findings reveal an important role for a MAPK (show MAPK1 Antibodies) pathway in light signal transduction.
ASR3 functions as a transcriptional repressor regulated by microbe-associated molecular patterns-activated MPK4 to fine-tune plant immune gene expression.
Mitogen-activated protein kinase 4 is a salicylic acid-independent regulator of growth but not of photosynthesis in Arabidopsis
Treatment of Arabidopsis with a membrane rigidifier, DMSO, causes MPK4 activation concomitantly with MEKK1 (show MAP3K1 Antibodies) and MKK2 (show MAP2K2 Antibodies) phosphorylation.
Data indicate that MEKK2 (show MAP3K2 Antibodies) is required for the mekk1 (show MAP3K1 Antibodies), mkk1 (show MAP2K1 Antibodies) mkk2 (show MAP2K2 Antibodies), and mpk4 autoimmune phenotypes.
Arabidopsis MPK4 can interact with and be phosphorylated by the cytokinesis-related MAP kinase (show MAPK1 Antibodies) kinase, AtMKK6 (show MAP2K6 Antibodies).
MPK4 activity was found to compromise effector-triggered immunity conditioned by the Toll Interleukin-1 Receptor-nucleotide binding (NB)-Leu-rich repeat (LRR) receptors RPS4 and RPP4 but not by the coiled coil-NB-LRR receptors RPM1 and RPS2.
Data suggest that the MEKK1 (show MAP3K1 Antibodies)-MKK1 (show MAP2K1 Antibodies)/MKK2 (show MAP2K2 Antibodies)-MPK4 kinase cascade negatively regulates MEKK2 (show MAP3K2 Antibodies) and activation of MEKK2 (show MAP3K2 Antibodies) triggers SUMM2-mediated immune responses.
Findings show that seedling survival of prolonged oxygen deprivation was improved in transgenics that ectopically overexpress MPK3 (show MAPK3 Antibodies), MPK4 and MPK6 (show MAPK6 Antibodies).
MKS1 function and subcellular location requires an intact N-terminus important for both MPK4 and WRKY33 interactions
Mitogen-activated protein kinase 4 is a member of the mitogen-activated protein kinase family. Tyrosine kinase growth factor receptors activate mitogen-activated protein kinases which then translocate into the nucleus where it phosphorylates nuclear targets.
