Summary
The protein encoded by this gene is a member of the MAP kinase family. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. The activation of this kinase requires its phosphorylation by upstream kinases. Upon activation, this kinase translocates to the nucleus of the stimulated cells, where it phosphorylates nuclear targets. Two alternatively spliced transcript variants encoding the same protein, but differing in the UTRs, have been reported for this gene. [provided by RefSeq].

- Serum induction initially stimulates MKL1 nuclear localization due to a decrease in G-actin levels, but MKL1 is then downregulated by nuclear export due to ERK1/2 phosphorylation.
- germinating but not resting conidia of A. fumigatus results in interleukin (IL)-8 synthesis that is controlled by phosphatidylinositol 3-kinase, p38 MAPK, and ERK1/2. MyD88 pathway is activated by A. fumigatus and leads to NF-kappaB activation

- The state of activation of components of mTOR, Ras/Raf kinase/ERK, and nuclear factor (NF)-kappaB signal transduction pathways, as well as cell cycle protein analyte correlates in gastric adenocarcinoma cases, was examined.
- MAPK-containing signaling complexes are positioned on sensitive promoters with their protein substrates to modulate transcription in situ in response to incoming signals
- A 3 amino acid domain (SPS) that is phosphorylated upon stimulation to induce nuclear translocation of ERK2, is identified.
- Crystal structures for inhibitor-kinase complexes in which the inhibitor has different binding orientations and hydrogen-bonding patterns with extracellular-signal regulated kinase 2 and insulin receptor tyrosine kinase, are reported.
- regulation of ERK1/2 by MKP-3 is countered by the complex regulation of MKP-3 by ERK1/2.
- pneumolysin selectively induced expression of MKP1 via a TLR4-dependent MyD88-TRAF6-ERK pathway, which inhibited the PAK4-JNK signaling pathway,leading to up-regulation of MUC5AC mucin production
- CysLTs induce MIP-1alpha and MIP-1beta production mediated by ERK via binding to the CysLT(1) receptor in human monocytes/macrophages.
- ERK2 CD domain mutation from a human cancer cell line enhanced anchorage-independent cell growth and abnormality in Drosophila.
- IL-17F may be involved in psoriasis via, in part, the activation of ERK1/2 and the induction of IL-8 in keratinocytes
- These results indicate that intron 1 of DUSP6 plays a crucial role in transcriptional regulation of DUSP6 in a feedback loop manner responding to MAPK1 via ETS2 in human cells.
- HMGB1 induced the activation of p38MAPK, ERK1/2 and Akt.
- the craniofacial and cardiac outflow tract defects observed in patients with a distal 22q11.2 micro-deletion are explained by deficiencies in neural crest autonomous ERK2 signaling.
- TC1 was involved in the mitogen-activated ERK1/2 signaling pathway and positively regulated G(1)- to S-phase transition of the cell cycle.
- The goal of the study was to delineate the specificity of RGS proteins modulating induced ERK phosphorylation.
- these results indicate the importance of C. burnetii modulation of host signaling and demonstrate a critical role for Akt and Erk1/2 in successful intracellular parasitism and maintenance of host cell viability.
- the molecular interactions of arrestin2 and arrestin3 and their individual domains with the components of the two MAPK cascades, ASK1-MKK4-JNK3 and c-Raf-1-MEK1-ERK2
- Fast regulation of AP-1 activity through interaction of lamin A/C, ERK1/2, and c-Fos at the nuclear envelope.
- EGF induces uPAR expression via ERK-1/2, AP-1, and NF-kappaB signaling pathways and, in turn, stimulates cell invasiveness in human gastric cancer AGS cells
