Function
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK1/ERK2 and MAPK3/ERK1 are the 2 MAPKs which play an important role in the MAPK/ERK cascade. They participate also in a signaling cascade initiated by activated KIT and KITLG/SCF. Depending on the cellular context, the MAPK/ERK cascade mediates diverse biological functions such as cell growth, adhesion, survival and differentiation through the regulation of transcription, translation, cytoskeletal rearrangements. The MAPK/ERK cascade also plays a role in initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors. About 160 substrates have already been discovered for ERKs. Many of these substrates are localized in the nucleus, and seem to participate in the regulation of transcription upon stimulation. However, other substrates are found in the cytosol as well as in other cellular organelles, and those are responsible for processes such as translation, mitosis and apoptosis. Moreover, the MAPK/ERK cascade is also involved in the regulation of the endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC); as well as in the fragmentation of the Golgi apparatus during mitosis. The substrates include transcription factors (such as ATF2, BCL6, ELK1, ERF, FOS, HSF4 or SPZ1), cytoskeletal elements (such as CANX, CTTN, GJA1, MAP2, MAPT, PXN, SORBS3 or STMN1), regulators of apoptosis (such as BAD, BTG2, CASP9, DAPK1, IER3, MCL1 or PPARG), regulators of translation (such as EIF4EBP1 and FXR1) and a variety of other signaling-related molecules (like ARHGEF2, DCC, FRS2 or GRB10). Protein kinases (such as RAF1, RPS6KA1/RSK1, RPS6KA3/RSK2, RPS6KA2/RSK3, RPS6KA6/RSK4, SYK, MKNK1/MNK1, MKNK2/MNK2, RPS6KA5/MSK1, RPS6KA4/MSK2, MAPKAPK3 or MAPKAPK5) and phosphatases (such as DUSP1, DUSP4, DUSP6 or DUSP16) are other substrates which enable the propagation the MAPK/ERK signal to additional cytosolic and nuclear targets, thereby extending the specificity of the cascade. Mediates phosphorylation of TPR in response to EGF stimulation. May play a role in the spindle assembly checkpoint. Phosphorylates PML and promotes its interaction with PIN1, leading to PML degradation. Phosphorylates CDK2AP2 (By similarity). Acts as a transcriptional repressor. Binds to a [GC]AAA[GC] consensus sequence. Repress the expression of interferon gamma-induced genes. Seems to bind to the promoter of CCL5, DMP1, IFIH1, IFITM1, IRF7, IRF9, LAMP3, OAS1, OAS2, OAS3 and STAT1. Transcriptional activity is independent of kinase activity.

- Sequence similarities
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
- Post-translational modifications
Phosphorylated upon KIT and FLT3 signaling (By similarity). Dually phosphorylated on Thr-185 and Tyr-187, which activates the enzyme. Undergoes regulatory phosphorylation on additional residues such as Ser-246 and Ser-248 in the kinase insert domain (KID) These phosphorylations, which are probably mediated by more than one kinase, are important for binding of MAPK1/ERK2 to importin-7 (IPO7) and its nuclear translocation. In addition, autophosphorylation of Thr-190 was shown to affect the subcellular localization of MAPK1/ERK2 as well. Ligand-activated ALK induces tyrosine phosphorylation. Dephosphorylated by PTPRJ at Tyr-187. Phosphorylation on Ser-29 by SGK1 results in its activation by enhancing its interaction with MAP2K1/MEK1 and MAP2K2/MEK2. DUSP3 and DUSP6 dephosphorylate specifically MAPK1/ERK2 and MAPK3/ERK1 whereas DUSP9 dephosphorylates a broader range of MAPKs. Dephosphorylated by DUSP1 and DUSP2 at Thr-185 and Tyr-187 (By similarity) (PubMed:16288922).

- Activity summary
ERK2 also known as Extracellular signal-Regulated Kinase 2 is a serine/threonine protein kinase in the mitogen-activated protein kinase (MAPK) family with a mass of approximately 42 kDa. This kinase is expressed in many cell types and tissues including the brain liver and lungs. ERK2 plays a significant role in cellular processes such as proliferation differentiation and survival. It is often analyzed using specific assays including ERK2 ELISA and examination of cell lysate samples to determine expression levels and activity.
- Biological function summary
ERK2 influences several key cellular functions. It functions as part of a signaling cascade transmitting signals from the exterior to the cell nucleus. In this cascade ERK2 is often part of a multi-protein complex that undergoes sequential phosphorylation. Through these mechanisms ERK2 regulates gene expression and is a pivotal component of the MAPK/ERK pathway ensuring the proper response to growth signals and stress stimuli.
- Pathways
ERK2 is a central component of the MAPK/ERK signaling pathway and the PI3K/AKT pathway. These pathways play critical roles in cell cycle regulation and apoptosis. ERK2 activation leads to its interaction with the MEK1/2 proteins which further allows the transmission of mitogenic signals. The interplay between ERK2 and related proteins like E460 often impacts cellular growth and development as it precisely controls the phosphorylation events within the pathway.
- Associated diseases and disorders
ERK2 is connected to certain types of cancer and neurodegenerative diseases. Aberrations in ERK2 signaling pathways are often linked to tumorigenesis where altered interaction with proteins such as Raf and MEK1/2 disrupts cell cycle regulation and apoptosis. In neurodegenerative disorders dysregulated ERK2 activity has been associated with proteins contributing to Alzheimer’s disease indicating its involvement in neuronal survival and stress response mechanisms.
