Also known as: CBY; arb1; Pgea1; PGEA14; 1110014P06Rik
Summary: Predicted to enable beta-catenin binding activity and protein homodimerization activity. Involved in cardiac muscle cell differentiation and fat cell differentiation. Acts upstream of or within cilium assembly; floor plate development; and negative regulation of canonical Wnt signaling pathway. Located in centriole and ciliary basal body. Is expressed in heart; liver; lung; and olfactory epithelium. Used to study otitis media and primary ciliary dyskinesia. Orthologous to human CBY1 (chibby 1, beta catenin antagonist).

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.
