Notch receptors are clustered and trans-endocytosed by Delta ligand cells. Confocal micrograph of a Delta expressing cell (left) interacting with a Notch expressing cell (right). Following interaction with Delta (blue), cell surface Notch (yellow) is clustered at cell-cell interfaces. Notch extracellular domain is detected within Delta cells (green) indicative of trans-endocytosis. Endocytosis of ligand while bound to Notch may produce a force sufficient to pull Notch apart and activate signaling.
