CC -!- FUNCTION: Serine/threonine-protein kinase involved in various processes
CC such as cell proliferation, differentiation, migration, transformation
CC and programmed cell death (PubMed:9393873). Extracellular stimuli such
CC as pro-inflammatory cytokines or physical stress stimulate the stress-
CC activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling
CC pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and
CC MAP2K7/MKK7 phosphorylate and activate MAPK8/JNK1. In turn, MAPK8/JNK1
CC phosphorylates a number of transcription factors, primarily components
CC of AP-1 such as JUN, JDP2 and ATF2 and thus regulates AP-1
CC transcriptional activity (PubMed:11602244). Phosphorylates the
CC replication licensing factor CDT1, inhibiting the interaction between
CC CDT1 and the histone H4 acetylase HBO1 to replication origins. Loss of
CC this interaction abrogates the acetylation required for replication
CC initiation. Promotes stressed cell apoptosis by phosphorylating key
CC regulatory factors including p53/TP53 and Yes-associates protein YAP1.
CC In T-cells, MAPK8 and MAPK9 are required for polarized differentiation
CC of T-helper cells into Th1 cells (PubMed:10811224). Contributes to the
CC survival of erythroid cells by phosphorylating the antagonist of cell
CC death BAD upon EPO stimulation. Mediates starvation-induced BCL2
CC phosphorylation, BCL2 dissociation from BECN1, and thus activation of
CC autophagy (By similarity). Phosphorylates STMN2 and hence regulates
CC microtubule dynamics, controlling neurite elongation in cortical
CC neurons (PubMed:21297631). In the developing brain, through its
CC cytoplasmic activity on STMN2, negatively regulates the rate of exit
CC from multipolar stage and of radial migration from the ventricular zone
CC (PubMed:21297631). Phosphorylates several other substrates including
CC heat shock factor protein 4 (HSF4), the deacetylase SIRT1, ELK1, or the
CC E3 ligase ITCH. Phosphorylates the CLOCK-ARNTL/BMAL1 heterodimer and
CC plays a role in the regulation of the circadian clock
CC (PubMed:22441692). Phosphorylates the heat shock transcription factor
CC HSF1, suppressing HSF1-induced transcriptional activity (By
CC similarity). Phosphorylates POU5F1, which results in the inhibition of
CC POU5F1's transcriptional activity and enhances its proteosomal
CC degradation (PubMed:29153991). Phosphorylates JUND and this
CC phosphorylation is inhibited in the presence of MEN1 (By similarity).
CC In neurons, phosphorylates SYT4 which captures neuronal dense core
CC vesicles at synapses (By similarity). Phosphorylates EIF4ENIF1/4-ET in
CC response to oxidative stress, promoting P-body assembly (By
CC similarity). Phosphorylates SIRT6 in response to oxidative stress,
CC stimulating its mono-ADP-ribosyltransferase activity (By similarity).
