Function

DLL1 is a human homolog of the Notch Delta ligand and is a member of the delta/serrate/jagged family. It plays a role in mediating cell fate decisions during hematopoiesis. It may play a role in cell-to-cell communication.^[5]

Interactions

Delta-like 1 has been shown to interact with NOTCH2.^[6][7][8]
