BioPAX pathway converted from "NICD3 binds to TACC3" in the Reactome database. NICD3 binds to TACC3 NICD3 binds to TACC3 Based on studies in mice, the intracellular domain of NOTCH3, NICD3, binds to transforming acidic coiled-coil protein-3 (TACC3). The interaction involves the ankyrin repeats of NOTCH3. The two proteins co-localize in the cytosol and possibly in the nucleus. TACC3 is implicated as a negative regulator of NOTCH signaling and may compete with NOTCH binding to RPBJ (Bargo et al. 2010).

Upon ligand activation through the released notch intracellular domain (NICD) it forms a transcriptional activator complex with RBPJ/RBPSUH and activates genes of the enhancer of split locus. Affects the implementation of differentiation, proliferation and apoptotic programs (By similarity).SUBUNIT Heterodimer of a C-terminal fragment N(TM) and a 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 NOTCH3. Interacts with PSMA1. Interacts with HIF1AN.TISSUE SPECIFICITY Ubiquitously expressed in fetal and adult tissues.DOMAIN The EGF-like domains 10 and 11 are required for binding the ligands JAG1 and DLL1.PTM Synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by a furin-like convertase in the trans-Golgi network before it reaches the plasma membrane to yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved by TNF-alpha converting enzyme (TACE) to yield a membrane-associated intermediate fragment called notch extracellular truncation (NEXT). This fragment is then cleaved by presenilin dependent gamma-secretase to release a notch-derived peptide containing the intracellular domain (NICD) from the membrane.PTM Phosphorylated.PTM Hydroxylated by HIF1AN.SIMILARITY Belongs to the NOTCH family.

Involved in the processes that regulate centrosome-mediated interkinetic nuclear migration (INM) of neural progenitors (By similarity). Acts as component of the TACC3/ch-TOG/clathrin complex proposed to contribute to stabilization of kinetochore fibers of the mitotic spindle by acting as inter-microtubule bridge. The TACC3/ch-TOG/clathrin complex is required for the maintenance of kinetochore fiber tension (PubMed:21297582, PubMed:23532825). May be involved in the control of cell growth and differentiation. May contribute to cancer (PubMed:14767476).SUBUNIT Interacts with microtubules. Interacts with CKAP5 independently of clathrin. Interacts with CKAP5 and clathrin forming the TACC3/ch-TOG/clathrin complex located at spindle inter-microtubules bridges; TACC3 (phosphorylated at Ser-558 by AURKA) and CLTC are proposed to form a composite microtubule interaction surface (PubMed:21297582, PubMed:23918938, PubMed:25596274). Interacts with CCDC100/CEP120. The coiled coil C-terminal region interacts with AH receptor nuclear translocator protein (ARNT) and ARNT2 (By similarity). Interacts with GCN5L2 and PCAF (PubMed:14767476).INDUCTION Up-regulated in various cancer cell lines.SIMILARITY Belongs to the TACC family.
