WebJun 23, 2024 · In quiescent cells, ERK is maintained in the cytoplasm by the activity of a limited number of proteins, including MEK1 (ref. 21), the ERK inhibitor PEA-15 (ref. 22) and the phosphatase MKP3 (ref. 23). The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell. The signal starts when a signaling molecule binds to the receptor on the cell surface and ends when the DNA in the nucleus expresses a protein and prod… WebLambda protein phosphatase can be used to remove both serine/threonine and tyrosine phosphorylation, and calf intestinal phosphatase phospho-tyrosine residues. 6.
