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.

Activity summary

ERK1 and ERK2 also known as MAPK3 and MAPK1 respectively are protein kinases involved in the mitogen-activated protein kinase (MAPK) signaling pathway. They share high sequence identity and exhibit similar functions. ERK1 has a molecular weight of approximately 44 kDa while ERK2 weighs around 42 kDa. Both are expressed ubiquitously in various tissues playing roles in diverse cellular processes. These proteins often detected through ERK1/2 western blot analyses present similar ERK protein size and ERK molecular weight characteristics relevant during protein expression studies.

Biological function summary

ERK1 and ERK2 play key roles in cell proliferation differentiation and survival. They form part of a cascade that includes upstream activators such as MEK1/2 and downstream targets including transcription factors. As components of the MAPK signaling complex ERK1/2 regulate gene expression through phosphorylation events impacting cellular responses to various stimuli. Their activation often hinges on growth factors cytokines and stress signals facilitating cellular adaptation to environmental changes.

Pathways

Regarding pathways ERK1/2 sit within the MAPK/ERK pathway and are significant in the Ras/Raf/MEK/ERK cascade one of the foremost signaling mechanisms in cells. They interact with several proteins including Ras and Raf which modulate their activation. This pathway is important for transmitting signals from the cell surface to the DNA in the cell nucleus impacting gene regulation and cell fate decisions. ERK1/2 proteins therefore serve as critical nodes linking extracellular signals to cellular responses ensuring balanced cell function.

Associated diseases and disorders

ERK1/2 play significant roles in cancer and neurodegenerative diseases. Their overactivation is often linked to oncogenic processes contributing to cell proliferation in cancers. Mutations or dysregulation within the MAPK/ERK pathway including ERK1/2 frequently associate with tumorigenesis. Additionally in neurodegenerative disorders like Alzheimer's disease altered ERK1/2 activity may impact neuronal survival and function often through interaction with amyloid-beta and tau proteins further illustrating their importance in disease pathophysiology.

    ERK1 + ERK2 Western blot staining using rabbit Anti-ERK1 + ERK2 antibody

    Anti-ERK1 (phospho T202+Y204) + ERK2 (phospho T185+Y187) antibody [EPR25015-F2] ab288063 was shown to specifically react with ERK1/2 (pT202+ Y204). The signal was significantly reduced after treat with 10 uM U0126.

    Samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5% BSA in TBS-0.1 % Tween® 20 (TBS-T).

    Anti-ERK1 (phospho T202+Y204) + ERK2 (phospho T185+Y187) antibody [EPR25015-F2] ab288063, ab184699 and Anti-Tubulin antibody [DM1A] - Loading Control (Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291) were incubated overnight at 4°C at 1/1000, 1/10000 and 1/5000 dilutions, respectively.

    Blots were developed with Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    All lanes: Western blot - Anti-ERK1 (phospho T202+Y204) + ERK2 (phospho T185+Y187) antibody [EPR25015-F2] (Anti-ERK1 (phospho T202+Y204) + ERK2 (phospho T185+Y187) antibody [EPR25015-F2] ab288063) at 1/1000 dilution
