背景信息

**Background of ERK1 Recombinant Protein**

ERK1 (Extracellular Signal-Regulated Kinase 1), also known as MAPK3. is a serine/threonine protein kinase central to the Ras-Raf-MEK-ERK signaling pathway. This evolutionarily conserved cascade regulates critical cellular processes, including proliferation, differentiation, survival, and apoptosis. ERK1 shares ~84% sequence identity with its paralog ERK2 (MAPK1), but subtle structural and functional differences influence their substrate preferences and cellular roles. ERK1 is typically activated by upstream kinases MEK1/2 through dual phosphorylation at Thr-202 and Tyr-204. enabling its translocation to the nucleus to phosphorylate transcription factors (e.g., Elk-1. c-Fos) or regulate cytoplasmic targets.

Recombinant ERK1 protein is produced using heterologous expression systems (e.g., *E. coli*, insect, or mammalian cells*) to ensure high purity and activity for research applications. Its production often involves tagging (e.g., GST, His-tag) for simplified purification and detection. This engineered protein serves as a vital tool for *in vitro* kinase assays, inhibitor screening, and mechanistic studies of MAPK signaling dysregulation linked to cancers, neurological disorders, and inflammatory diseases.

Studies using recombinant ERK1 have clarified its role in feedback regulation, substrate specificity, and crosstalk with other pathways (e.g., PI3K/AKT). Despite overlapping functions with ERK2. ERK1’s lower abundance and distinct interaction networks suggest unique regulatory contributions, making it a target for selective therapeutic strategies. Continued research with recombinant ERK1 aims to develop targeted therapies and biomarkers for diseases driven by aberrant MAPK signaling.
