Supplementary information

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.

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.

Target data

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.
