MAPK/ERK pathway

Under development!!!

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.

• Cell surface receptors that can activate this pathway via GRB2:

Epidermal Growth Factor Receptor (EGFR; see also Epidermal growth factor). EGFR belongs to Receptor tyrosine kinases, class I.

Trk A/B: High affinity nerve growth factor receptor (TrkA). TrkB tyrosine kinase receptor. See also Neurotrophin.

Fibroblast growth factor receptor

Platelet-derived growth factors and receptors

• Growth factor receptor-bound proteins (GRB) are adaptor proteins. GRBs contain SH2, Ras-associated (RA) and pleckstrin homology (PH) domains. For additional details on GRB10 see Grb10 SH2 Domain.

• Rho guanine nucleotide exchange factor.

• Ras subfamily: GTPase KRas and Allosteric modulation of H-Ras GTPase.
