Summary: Predicted to enable Wnt receptor activity and Wnt-protein binding activity. Acts upstream of or within canonical Wnt signaling pathway; eye field cell fate commitment involved in camera-type eye formation; and neurogenesis. Predicted to be located in membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including digestive system; mesoderm; nervous system; neural keel; and pectoral fin. Orthologous to human FZD8 (frizzled class receptor 8). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
