Summary: Predicted to enable several functions, including alpha-catenin binding activity; cadherin binding activity; and protein kinase C binding activity. Involved in maintenance of protein localization at cell tip. Acts upstream of or within cell-cell adhesion and heart development. Located in desmosome; intercalated disc; and intermediate filament. Is expressed in brain; cardiac muscle tissue; and telencephalon.

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.
