Summary: Enables PDZ domain binding activity; Wnt receptor activity; and Wnt-protein binding activity. Involved in several processes, including Wnt signaling pathway; instar larval or pupal development; and neuron differentiation. Located in nucleus and plasma membrane. Part of Wnt signalosome. Colocalizes with early endosome and late endosome. Is expressed in several structures, including anterior-posterior subdivision of organism; gut section; somatic cell of testis; synaptic neuropil domain; and visceral mesoderm derivative. Orthologous to several human genes including FZD5 (frizzled class receptor 5). [provided by Alliance of Genome Resources, Nov 2024]

What's a GeneRIF?

cells located outside the reach of extracellular Wg depend on the Frizzled2 receptor to maintain signaling. Frizzled2 expression is increased in the absence of Wg secretion and is required to maintain signaling and cell survival in NRT-wg wing discs.
Title: Robust Wnt signaling is maintained by a Wg protein gradient and Fz2 receptor activity in the developing Drosophila wing.
Maturation of a central brain flight circuit in Drosophila requires Fz2 and Ca2+ signaling.
Title: Maturation of a central brain flight circuit in Drosophila requires Fz2/Ca²⁺ signaling.
The heterotrimeric G protein Go functions as a transducer of Wingless-Frizzled 2 signaling in the synapse and Ankyrin 2 as a target of Go signaling required for neuromuscular junction formation
Title: Heterotrimeric Go protein links Wnt-Frizzled signaling with ankyrins to regulate the neuronal microtubule cytoskeleton.
Study finds that C-terminal fragments of the Wg receptor DFz2 accumulate in nuclear foci in association with large RNA granules localizing to the space between the inner & and outer nuclear membranes; granules are found at of inner membrane invaginations, are bounded by LamC, and can be seen leaving the nucleus.
Title: Nuclear envelope budding enables large ribonucleoprotein particle export during synaptic Wnt signaling.
Knockdown of Tc-fz1 alone interfered with the formation of the proximo-distal and the dorso-ventral axes during leg development, whereas no effect was observed with single Tc-fz2 or Tc-fz4 RNAi knockdowns.
Title: A context-dependent combination of Wnt receptors controls axis elongation and leg development in a short germ insect.
Wnt-activated growth of the postsynaptic membrane is mediated by the synapse-to-nucleus translocation and active nuclear import of Fz2-C via a selective Importin-beta11/alpha2 pathway.
Title: The nuclear import of Frizzled2-C by Importins-beta11 and alpha2 promotes postsynaptic development.
concluded that, at synapses, Wingless signal transduction occurs through the nuclear localization of DFrizzled2-C for potential transcriptional regulation of synapse development
Title: Wingless signaling at synapses is through cleavage and nuclear import of receptor DFrizzled2.
Frizzled2 achieves ligand capture and internalization, whereas Arrow, and perhaps downstream signalling, are essential for lysosomal targeting.
Title: Arrow (LRP6) and Frizzled2 cooperate to degrade Wingless in Drosophila imaginal discs.
subcellular Fz localization, through the association with other membrane proteins, is a critical aspect in regulating the signaling specificity within the Wnt/Fz signaling pathways
Title: Subcellular localization of frizzled receptors, mediated by their cytoplasmic tails, regulates signaling pathway specificity.
DFz2 functions as an endocytic receptor for Wingless in the Drosophila wing
Title: Endocytic trafficking of Wingless and its receptors, Arrow and DFrizzled-2, in the Drosophila wing.
