Lineage: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora
Also known as: CG1916; D-wnt-2; Dm DWnt2; Dm-2; Dmel\CG1916; Dwnt-2; DWnt-2; dWnt2; Dwnt2; DWnt2; Wnt; wnt-2; Wnt-2; wnt2
Summary: Enables frizzled binding activity. Involved in several processes, including axon extension; canonical Wnt signaling pathway; and germ-line stem-cell niche homeostasis. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including labrum; male genital disc primordium; proctodeum; segment; and seminal vesicle. Human ortholog(s) of this gene implicated in Fuhrmann syndrome; Mullerian aplasia and hyperandrogenism; and Schinzel type phocomelia. Orthologous to several human genes including WNT7B (Wnt family member 7B). [provided by Alliance of Genome Resources, Dec 2024]

Wnt2 overexpression protects against PINK1 mutantinduced mitochondrial dysfunction and oxidative stress.

We discovered an otk paralog (otk2, CG8964), which is co-expressed with otk throughout embryonic and larval development. Otk and Otk2 bind to each other and form complexes with Frizzled, Frizzled2 and Wnt2, pointing to a function as Wnt co-receptors.

Mutations in Wnt2 alter presynaptic motor neuron morphology and presynaptic protein localization at the neuromuscular junction.

Data show that Drosophila Naked cuticle (Nkd) engages the nuclear import adaptor Importin-alpha3 to antagonize Wnt/beta-catenin signaling.

DWnt-2 promotes correct patterning of direct flight muscles through a mechanism that is independent of the attachment site differentiation initiated by stripe.
Title: Direct flight muscles in Drosophila develop from cells with characteristics of founders and depend on DWnt-2 for their correct patterning.
