ERK1 + ERK2
NCBI and Uniprot Product Information
Uniprot Description
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 plays also 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 a variety of other signaling-related molecules (like ARHGEF2, 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.

Catalytic activity: ATP + a protein = ADP + a phosphoprotein.
Cofactor: Magnesium
By similarity.
Enzyme regulation: Phosphorylated by MAP2K1/MEK1 and MAP2K2/MEK2 on Thr-203 and Tyr-205 in response to external stimuli like insulin or NGF. Both phosphorylations are required for activity. This phosphorylation causes dramatic conformational changes, which enable full activation and interaction of MAPK1/ERK2 with its substrates. Dephosphorylated and inactivated by DUSP3, DUSP6 and DUSP9.
Subunit structure: Binds both upstream activators and downstream substrates in multimolecular complexes. Found in a complex with at least BRAF, HRAS1, MAP2K1/MEK1, MAPK3 and RGS14. Interacts with TPR
By similarity. Interacts with ADAM15, ARRB2, CANX, DAPK1 (via death domain), HSF4, IER3, MAP2K1/MEK1, NISCH, and SGK1
By similarity. Interacts with MORG1, PEA15 and MKNK2. MKNK2 isoform 1 binding prevents from dephosphorylation and inactivation. Ref.11 Ref.13 Ref.15
Subcellular location: Cytoplasm. Nucleus. Note: Autophosphorylation at Thr-207 promotes nuclear localization
By similarity. PEA15-binding redirects the biological outcome of MAPK3 kinase-signaling by sequestering MAPK3 into the cytoplasm. Ref.11 Ref.12
Domain: The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Post-translational modification: Dually phosphorylated on Thr-203 and Tyr-205, which activates the enzyme. Ligand-activated ALK induces tyrosine phosphorylation
By similarity. Dephosphorylated by PTPRJ at Tyr-205
By similarity. Autophosphorylated on threonine and tyrosine residues in vitro. Phosphorylated upon FLT3 and KIT signaling
By similarity. Ref.9 Ref.10 Ref.14 Ref.20
Sequence similarities: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.Contains 1 protein kinase domain.

Product Notes
The ERK1 + ERK2 mapk3 (Catalog #AAA395804) is an Antibody produced from Sheep and is intended for research purposes only. The product is available for immediate purchase. The ERK1 + ERK2 reacts with Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's ERK1 + ERK2 can be used in a range of immunoassay formats including, but not limited to, Immunoprecipitation (IP). Researchers should empirically determine the suitability of the ERK1 + ERK2 mapk3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "ERK1 + ERK2, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
