WebbUpon reaching the cell surface, the ECDs of Notch receptors from the signal-receiving cell interact with the ligands from the neighboring signal-sending cell. This interaction is followed by the endocytosis of the trans-ligand on the signal-sending cell.

WebbReceptors are protein molecules in the target cell or on its surface that bind ligand. There are two types of receptors, internal receptors and cell-surface receptors. Internal receptors In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. These signals are typically chemical messengers which bind to a receptor and cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell. There are three main ways the action of the rece…
