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.
a critical role for Erk3 (show RYK Antibodies) in the establishment of fetal growth potential and pulmonary function in the mouse
Data show that in contrast to ERK3 (show RYK Antibodies), 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 (show RYK Antibodies).
H2S inhibited the opening of stomata under cold stress, which required the participation of MPK4. In conclusion, MPK4 is a downstream component of H2S-related cold-stress resistance, and H2S and MPK4 both regulated the cold response genes and stomatal movement to response the cold stress.
Proteome changes associated with MPK4 and MPK6 (show MAPK6 Antibodies) deficiency in Arabidopsis roots.
AvrRpt2 specifically blocks the flagellin (show FliC Antibodies)-induced activation of MPK4.
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.
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.
