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.

ERK1 also known as MAPK3 is an extracellular signal-regulated kinase involved in transmitting signals from the cell surface to the nucleus. This protein has a molecular mass of about 44 kDa. ERK1 expresses in various tissue types with higher expression in the brain heart and skeletal muscle. Researchers often study ERK1 in the context of its role in cellular signaling due to its involvement in critical regulatory functions.
ERK1 plays a significant role in cell cycle regulation differentiation and proliferation. It forms part of the MAPK signaling cascade becoming activated through a phosphorylation event. In its activated form ERK1 translocates to the nucleus where it phosphorylates target substrates. ERK1 often functions in conjunction with its homolog ERK2 to mediate these cellular processes marking it as an essential player in growth factor signaling.
ERK1 functions primarily within the MAPK/ERK signaling pathway a major conduit for transmitting proliferative signals from growth factor receptors. ERK1 interacts with proteins like MEK1/2 which phosphorylate and activate ERK1 in response to extracellular stimuli. Another critical pathway involving ERK1 is the Ras-Raf-MEK-ERK cascade which regulates various cellular outcomes. This connection to the Ras family highlights its importance in signal transduction and reinforces its position in critical cellular processes.
Aberrant activation of ERK1 connects to diseases such as cancer and cardiovascular disorders. In cancer the dysregulation of the MAPK/ERK pathway often through mutations affecting Ras or Raf proteins leads to uncontrolled cell proliferation. ERK1's involvement in cardiovascular diseases links to its role in hypertrophic signaling in cardiac cells where altered ERK1 activity can contribute to pathological cardiac remodeling. Understanding these interactions can aid in developing therapeutic strategies targeting the MAPK/ERK signaling pathway.
