Function
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway (PubMed:34497368). 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 a variety of other signaling-related molecules (like ARHGEF2, DEPTOR, FRS2 or GRB10) (PubMed:35216969). 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.

Notes
Abcam's ERK1 (phospho T202 + Y204) + ERK2 (phospho T185 + Y187) + Total ELISA kit is designed for the semi-quantitative measurement of ERK1/2 (pT202/Y204) and Total ERK1/2 protein in Human and mouse cells.
The SimpleStep ELISA™ employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.
ASSAY SPECIFICITY
The ERK1/2 (pT202/Y204) assay detects endogenous levels of ERK1/2 (GenBank Accessions NP 002737.2 [ERK1], NP 620407 [ERK2]) in cellular lysates, only when phosphorylated at Thr202/Tyr204.
The ERK1/2 Total assay detects endogenous levels of ERK1/2 (GenBank Accessions NP 002737.2 [ERK1], NP 620407 [ERK2]) in cellular lysates, irrespective of phosphorylation status.
SPECIES REACTIVITY
This kit detects ERK1/2 (pT202/Y204) and ERK1/2 Total in Human and mouse cell culture extracts. Detection in rat samples is also expected. Other species should be tested on a case-by-case basis.
Serum and plasma samples have not been tested with this kit.
As of October 2019, this kit was reformulated with new antibodies to maintain continued long term supply.
Estimated sensitivity: Phospho-ERK (Thr202/Tyr204): 0.1 ng/mL (tested with recombinant protein), Total ERK1/2: 0.6 ng/mL (tested with recombinant protein)
Range: Phospho-ERK (Thr202/Tyr204): 0.2-20ng/mL, Total ERK1/2: 0.6-60 ng/mL

Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
ERK1 and ERK2 also known as p44 and p42 MAPK respectively are important proteins in the MAP kinase signaling pathway. They are expressed in various tissues with significant presence in the brain lungs and skin. ERK1 has a molecular weight of approximately 44 kDa while ERK2 has a molecular weight of around 42 kDa. Both proteins become activated through phosphorylation which is essential for their function in cellular processes.
- Biological function summary
ERK1 and ERK2 serve as key players in cellular growth differentiation and survival. They form part of a complex cascade where they transduce signals from the cell membrane to the nucleus after activation by phosphorylation. This phosphorylation enables them to modify various downstream targets involved in regulating gene expression and cellular response to external stimuli.
- Pathways
ERK1 and ERK2 are critical components of the MAPK/ERK pathway and the Ras-Raf-MEK-ERK signaling cascade. These pathways regulate a multitude of cellular activities including proliferation and differentiation. In the MAPK/ERK pathway proteins like Ras and Raf serve as upstream activators of ERK1 and ERK2. Both ERK1 and ERK2 also interact with other signaling proteins such as MEK1/2 which directly phosphorylates and activates them.
- Associated diseases and disorders
Dysregulation of ERK1 and ERK2 is associated with various pathologies including cancer and neurodegenerative diseases. Abnormal activation of these proteins often leads to uncontrolled cell proliferation contributing to oncogenesis. For instance mutations in proteins like Ras which regulate ERK1 and ERK2 can result in continuous activation and lead to tumor formation. Furthermore altered ERK1 and ERK2 signaling is linked to neurodegeneration impacting neuronal survival and function.
