Also known as: Fz8
Summary: Enables several functions, including PDZ domain binding activity; Wnt receptor activity; and Wnt-protein binding activity. Involved in Wnt signaling pathway. Acts upstream of or within several processes, including T cell differentiation in thymus; canonical Wnt signaling pathway; and positive regulation of JUN kinase activity. Located in plasma membrane. Part of Wnt-Frizzled-LRP5/6 complex. Is active in neuronal dense core vesicle. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human FZD8 (frizzled class receptor 8). [provided by Alliance of Genome Resources, Nov 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.
