    Summary
    This gene encodes a protein that belongs to the vinculin/alpha-catenin family. The encoded protein plays a role in cell-cell adhesion in muscle cells. Mutations in this gene are associated with arrhythmogenic right ventricular dysplasia, familial 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

    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.

      Transcript Variant: This variant (3) has multiple differences compared to variant 1. These differences result in distinct 5' and 3' UTRs and cause translation initiation at an alternate start codon compared to variant 1. The encoded protein (isoform b) has a longer N-terminus, a distinct C-terminus, and is shorter compared to isoform a.
