Epidermal Growth Factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor epidermal growth factor receptor (EGFR) which triggers ligand-induced dimerization which activates the intrinsic protein-tyrosine kinase activity of EGFR. This in turn initiates a signal transduction cascade that results in various biochemical changes within the cell being targeted by EGF. This ultimately leads to DNA synthesis and cell proliferation. Members of this protein family are all similar due to their shared structural and functional characteristics. Each member of the EGF family have at least one common structural motif, the EGF domain, which is character …

Notch signalling pathway review The Notch signalling pathway is a highly conserved intercellular signalling pathway that regulates various cellular processes. The Notch receptor is a transmembrane protein that is activated by the binding of Notch ligands, which are secreted proteins. There are four known Notch ligands: Jagged, Delta, Serrate, and Lag-related protein. Notch receptors are activated by the binding of a Notch ligand to the receptor's extracellular domain. This binding results in the proteolytic cleavage of the receptor by furin-like proteases. The cleaved Notch intracellular domain (NICD) of the receptor translocates to the nucleus where it interacts with transcri …
