MAPK1/ERK2 Protein, Human (Active, Flag-His)

ERK2 Protein, a key component of the MAPK/ERK cascade, regulates diverse cellular processes such as transcription, translation, mitosis, apoptosis, endosomal dynamics, and Golgi apparatus fragmentation. Through phosphorylation, it modulates substrates including transcription factors, cytoskeletal elements, apoptosis regulators, translation regulators, protein kinases, and phosphatases. MAPK1 Protein, Human (Active, Flag, His) is the recombinant human-derived MAPK1, expressed by E. coli, with N-His, N-Flag labeled tag.

The MAPK/ERK cascade plays a crucial role in the regulation of various cellular processes, including transcription, translation, mitosis, apoptosis, endosomal dynamics, and Golgi apparatus fragmentation. It achieves this by phosphorylating a multitude of substrates, including transcription factors, cytoskeletal elements, regulators of apoptosis, regulators of translation, protein kinases, and phosphatases.

The activity was measured by off-chip mobility shift assay(MSA). The enzyme was incubated with fluorecence-labeled substrate and Mg(or Mn)/ATP. The phosphorylated and unphosphorylated substrates were separated and detected by MSA device. When the protein concentration is 25 nM, the conversion rate is about 35%.
