Summary: Predicted to enable co-receptor binding activity and receptor antagonist activity. Acts upstream of or within several processes, including animal organ development; hepatic duct development; and sensory epithelium regeneration. Located in cytoplasm and extracellular region. Is expressed in several structures, including embryonic structure; median fin fold; mesoderm; pharyngeal arch; and sensory system. Human ortholog(s) of this gene implicated in anodontia. Orthologous to human DKK1 (dickkopf WNT signaling pathway inhibitor 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
