ERK1 Protein, Human (GST)

ERK1 protein is an important serine/threonine kinase in the MAP kinase pathway and cooperates with MAPK1/ERK2 to activate the MAPK/ERK cascade. Stimulated by KIT and KITLG/SCF, this pathway plays a key role in cell growth, adhesion, survival, and differentiation. ERK1 Protein, Human (GST) is the recombinant human-derived ERK1 protein, expressed by E. coli , with N-GST labeled tag. The total length of ERK1 Protein, Human (GST) is 378 a.a., .

ERK1, a serine/threonine kinase, stands as a vital component in the MAP kinase signal transduction pathway, working in concert with MAPK1/ERK2 to orchestrate the MAPK/ERK cascade. This pathway, activated by stimuli such as KIT and KITLG/SCF, plays a pivotal role in diverse biological functions, including cell growth, adhesion, survival, and differentiation. ERK1, along with MAPK1/ERK2, influences transcription, translation, and cytoskeletal rearrangements, while also contributing to the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells through the phosphorylation of numerous transcription factors. With approximately 160 substrates identified for ERKs, their targets span various cellular compartments, participating in processes such as transcription regulation, translation, mitosis, and apoptosis. Additionally, the MAPK/ERK cascade is implicated in endosomal dynamics, lysosome processing, endosome cycling through the perinuclear recycling compartment (PNRC), and the fragmentation of the Golgi apparatus during mitosis. Noteworthy substrates include transcription factors, cytoskeletal elements, regulators of apoptosis, regulators of translation, as well as diverse signaling-related molecules, protein kinases, and phosphatases, thereby extending the cascade's specificity and amplifying its impact on cellular responses.
