Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Receptor for Wnt proteins. Most of frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. Required to coordinate the cytoskeletons of epidermal cells to produce a parallel array of cuticular hairs and bristles.SUBUNIT Interacts with ATP6AP2.SUBCELLULAR LOCATION Expression starts at stage 6 in all cells between 15 and 70 per cent of egg length, including the invaginating cells of the ventral furrow. Stripe pattern is emerging by early stage 8. From stage 9 and continuing throughout embryogenesis, expression is seen in the developing CNS. At stage 10, expressed in 15 stripes in the presumptive head and trunk regions, in the posterior midgut primordium, in a subset of cells of anterior midgut invagination and in the procephalic lobe. At stage 12, expression declines in epidermis and increases in the midgut and visceral mesoderm. At stage 17, only expressed in the CNS, hindgut and dorsal vessel.DOMAIN Lys-Thr-X-X-X-Trp motif interacts with the PDZ domain of Dvl (Disheveled) family members and is involved in the activation of the Wnt/beta-catenin signaling pathway.DOMAIN The FZ domain is involved in binding with Wnt ligands.SIMILARITY Belongs to the G-protein coupled receptor Fz/Smo family.
