NOTCH2

This gene encodes a member of the Notch family. Members of this Type 1 transmembrane protein family share structural characteristics including an extracellular domain consisting of multiple epidermal growth factor-like (EGF) repeats, and an intracellular domain consisting of multiple, different domain types. Notch family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling network is an evolutionarily conserved intercellular signaling pathway which regulates interactions between physically adjacent cells. In Drosophilia, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signaling pathway that plays a key role in development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remain to be determined. This protein is cleaved in the trans-Golgi network, and presented on the cell surface as a heterodimer. This protein functions as a receptor for membrane bound ligands, and may play a role in vascular, renal and hepatic development. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

Interaction

Heterodimer of a C-terminal fragment N(TM) and an N-terminal fragment N(EC) which are probably linked by disulfide bonds (By similarity). Interacts with MAML1, MAML2 and MAML3 which act as transcriptional coactivators for NOTCH2. Interacts with RELA/p65 (By similarity). Interacts with HIF1AN. Interacts (via ANK repeats) with TCIM, the interaction inhibits the nuclear translocation of NOTCH2 N2ICD (PubMed:25985737). Interacts with CUL1, RBX1, SKP1 and FBXW7 that are SCF(FBXW7) E3 ubiquitin-protein ligase complex components (PubMed:29149593). Interacts with MINAR1; this interaction increases MINAR1 stability and function (PubMed:29329397). Interacts with NOTCH2NL (NOTCH2NLA, NOTCH2NLB and/or NOTCH2NLC); leading to enhance Notch signaling pathway in a non-cell-autonomous manner (PubMed:29856954). Interacts with MDK; this interaction mediates a nuclear accumulation of NOTCH2 and therefore activation of NOTCH2 signaling leading to interaction between HES1 and STAT3 (PubMed:18469519).
