DESCRIPTION

Also known as NOTCH_DROME, N. Essential signaling protein which has a major role in many developmental processes (PubMed:3935325). Functions as a receptor for membrane-bound ligands Delta and Serrate to regulate cell-fate determination (PubMed:10935637, PubMed:15620650, PubMed:12909620, PubMed:18243100). Upon ligand activation, and releasing from the cell membrane, the Notch intracellular domain (NICD) forms a transcriptional activator complex with Su(H) (Suppressor of hairless) and activates genes of the E(spl) complex (PubMed:7671825). Regulates oogenesis, the differentiation of the ectoderm and the development of the central and peripheral nervous system, eye, wing disk, muscles and segmental appendages such as antennae and legs, through lateral inhibition or induction (PubMed:11719214, PubMed:12369105, PubMed:3935325). Regulates neuroblast self-renewal, identity and proliferation through the regulation of bHLH-O proteins; in larval brains, involved in the maintenance of type II neuroblast self-renewal and identity by suppressing erm expression together with pnt; might also regulate dpn expression through the activation of the transcriptional regulator Su(H) (PubMed:27151950, PubMed:28899667, PubMed:20152183, PubMed:18342578, PubMed:23056424, PubMed:21262215). Homomer. Interacts with Su(H) when activated. Interacts with Dx via its ANK repeats. Interacts with Dl via the EGF repeats and the Dl EGF repeats. Interacts with Nedd4 and Su(dx). Interacts with O-fut1; the interaction glycosylates N and transports N to early endosomes. Interacts with Akap200; the interaction stabilizes N/Notch protein levels by preventing Cbl-mediated ubiquitination and subsequent lysosomal degradation of N/Notch (PubMed:29309414).
