Summary: Enables beta-catenin binding activity and molecular adaptor activity. Involved in several processes, including embryonic development via the syncytial blastoderm; oogenesis; and regionalization. Located in several cellular components, including apical cortex; basal cortex; and cleavage furrow. Part of beta-catenin destruction complex. Is active in cytosol. Colocalizes with actin filament. Is expressed in several structures, including epithelial cell; ganglia; germ layer; germline stem cell; and imaginal disc. Human ortholog(s) of this gene implicated in several diseases, including Sotos syndrome 3; autosomal recessive intellectual developmental disorder 74; carcinoma (multiple); gastrointestinal system cancer (multiple); and reproductive organ cancer (multiple). Orthologous to human APC (APC regulator of WNT signaling pathway) and APC2 (APC regulator of WNT signaling pathway 2). [provided by Alliance of Genome Resources, Dec 2024]

mitochondrial energy production, Nrg/Ank2, branched actin generated by Arp2/3 and Fz/G proteins/Axin function as four modules that control localization of the microtubule regulator Apc2 to its site of action in dendrite branch points.
Title: Identification of Proteins Required for Precise Positioning of Apc2 in Dendrites.
Data suggest that brain tumor protein (Brat) promotes midline crossing through directing the localization or stability of Adenomatous polyposis coli-2 (Apc2) at the plus ends of microtubules in navigating commissural axons.
Title: Brain Tumor promotes axon growth across the midline through interactions with the microtubule stabilizing protein Apc2.
This study provides new perspectives on the cellular effects of APC that might lead to a deeper understanding of its role in development.
Title: Proteomic analysis reveals APC-dependent post-translational modifications and identifies a novel regulator of β-catenin.
APC2 self-association is required for WNT destructosome activity in the Drosophila embryo.
Title: Self-association of the APC tumor suppressor is required for the assembly, stability, and activity of the Wnt signaling destruction complex.
Germline specific overexpression of Adenomatous Polyposis Coli 2 rescued germline stem cell loss in chic hypomorphs, suggesting an additive role of APC2 and F-actin in maintaining the adherens junctions that anchor germline stem cells to the niche.
Title: The actin-binding protein profilin is required for germline stem cell maintenance and germ cell enclosure by somatic cyst cells.
APC2 protects genome stability by modulating mitotic fidelity through regulation of the cytoskeleton.
Title: APC2 and Axin promote mitotic fidelity by facilitating centrosome separation and cytoskeletal regulation.
These data suggest that APC2 does not have to shuttle into the nucleus or localize to a particular subcellular location to regulate Wnt signaling.
Title: Regulation of Wnt signaling by the tumor suppressor adenomatous polyposis coli does not require the ability to enter the nucleus or a particular cytoplasmic localization.
Data show that a loss of function for dapc1 or both dapc1 and dapc2 (dapc) in ovary border (BC) and adjacent follicle cells impaired BC delamination, and this mutant phenotype can be rescued upon overexpression of either dapc1 or dapc2.
Title: Drosophila apc regulates delamination of invasive epithelial clusters.
Data show that although cortical localization is required for the APC2 function in organizing actin, cortical localization is dispensable for its role in regulating Wnt signaling.
Title: Cortical localization of APC2 plays a role in actin organization but not in Wnt signaling in Drosophila.
APC2 and DIA function in a novel complex that affects actin directly, rather than through an effect on microtubules
Title: A novel role for an APC2-Diaphanous complex in regulating actin organization in Drosophila.
