Summary: Predicted to enable several functions, including alpha-catenin binding activity; cadherin binding activity; and transcription coactivator activity. Involved in canonical Wnt signaling pathway and determination of dorsal identity. Acts upstream of or within convergent extension and dorsal/ventral axis specification. Located in nucleus. Is expressed in corneal endothelium; interneuromast cell; neuromast; secondary posterior lateral line primordium; and vertebral column. Human ortholog(s) of this gene implicated in several diseases, including autosomal dominant non-syndromic intellectual disability 19; exudative vitreoretinopathy 7; hepatocellular carcinoma (multiple); nephroblastoma; and pilomatrixoma. Orthologous to human CTNNB1 (catenin beta 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.
