Notch signaling pathway in zebrafish and mouse. Upon interaction between the Notch receptor and its ligands Jagged/Delta, and through several subsequent cleavage steps the NICD is released and translocates to the nucleus. In the nucleus, the NICD, together with Rbpj, activates the expression of the downstream genes Hes (mouse) and her (zebrafish). The Hes/Her proteins bind as homodimers to the promoter of proneural genes to inhibit neuronal fate. Additionally, the dimer can bind to its own promoter, resulting in a negative auto-regulation. bHLH, basic helix-loop-helix; Her, human epidermal growth factor receptor; Hes, Hairy/enhancer of split; NEXT, Notch extracellular truncation; NICD, Notch intracellular domain; Rbpj, Recombining binding protein suppressor of hairless.
