Anti-SAP30 like antibodies are used for the immunodetection of the protein encoded by the SAP30L gene. In humans, the canonical protein has a reported length of 183 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. It is notably expressed in the brain and ovary, and at lower levels in the heart, small intestine, lung, kidney, skeletal muscle, stomach and spleen. A member of the SAP30 protein family, it is known to function as transcription repressor, probably via its interaction with histone deacetylase complexes. Other names for this target antigen include HCV non-structural protein 4A-transactivated protein 2, Sin3A associated protein p30-like, sin3 corepressor complex subunit SAP30L, and histone deacetylase complex subunit SAP30L. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SAP30 like antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
