AOS5,AOVD1,hN1,neurogenic locus notch homolog protein 1,notch 1,Notch homolog 1, translocation-associated,TAN1,translocation-associated notch protein TAN-1.
Functions as a receptor for membrane-bound ligands Jagged1, Jagged2 and Delta1 to regulate cell-fate determination. Upon ligand activation through the released notch intracellular domain (NICD) it forms a transcriptional activator complex with RBPJ/RBPSUH
