Interaction between the receptor and ligand induces a couple of proteolytic cleavages causing the release of the intracellular domain part of the receptor from the cell membrane. This interaction is mediated by consecutive enzymatic reactions. The intracellular domain then translocates to the nucleus part of the cell and forms a complex with a protein called RBPJ. This reaction leads to displacement of a histone deacetylase-co-compressor complex from the RBPJ protein molecule and then inclusion
