Anti-ARVCF delta catenin family member antibodies are used for the immunodetection of the protein encoded by the ARVCF gene. In humans, the canonical protein has a reported length of 962 amino acid residues and a mass of 104.6 kDa. Its subcellular localization is in the nucleus, cell junctions, and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be found in all the examined tissues including heart, brain, liver and kidney. A member of the Beta-catenin protein family, it is said to contribute to the regulation of alternative splicing of pre-mRNAs. Other names for this target antigen include armadillo repeat gene deleted in velocardiofacial syndrome, armadillo repeat protein deleted in velo-cardio-facial syndrome, and splicing regulator ARVCF. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
