Summary: Enables alpha-catenin binding activity. Acts upstream of or within cell-cell adhesion; desmosome assembly; and skin development. Located in several cellular components, including Z disc; adherens junction; and intermediate filament. Part of catenin complex. Is active in cornified envelope. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system; and sensory organ. Used to study arrhythmogenic right ventricular dysplasia 12 and epidermolytic hyperkeratosis. Human ortholog(s) of this gene implicated in cardiomyopathy (multiple); palmoplantar keratosis (multiple); renal cell carcinoma; and reproductive organ cancer (multiple). Orthologous to human JUP (junction plakoglobin). [provided by Alliance of Genome Resources, Jul 2025]

FLG and DST support melanoma cell growth in vitro and in vivo. Growth effects of JUP were only evident in vivo, and may be mediated, in part, by enhancing angiogenesis. In addition, growth-promoting effects of FLG and DST in vitro suggest that these genes may also support melanoma cell proliferation through angiogenesis-independent pathways.

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.
