Anti-SYNTROPHIN ALPHA 1 antibodies are used for the immunodetection of the protein encoded by the SNTA1 gene. In humans, the canonical protein has a reported length of 505 amino acid residues and a mass of 53.9 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be highly expressed in skeletal muscle and heart. A member of the Syntrophin protein family, it is a reported adaptor protein that binds to and probably organizes the subcellular localization of a variety of membrane proteins. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Long QT syndrome. Other names for this target antigen include SNT1, TACIP1, dJ1187J4.5, alpha-1-syntrophin, 59 kDa dystrophin-associated protein A1 acidic component 1, and LQT12. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
