Anti-obscurin like cytoskeletal adaptor 1 antibodies are used for the immunodetection of the protein encoded by the OBSL1 gene. In humans, the canonical protein has a reported length of 1896 amino acid residues and a mass of 206.9 kDa. Its subcellular localization is in the Golgi and cytoplasm. Alternative splicing is reported to yield 4 different isoforms for this protein. It is found to be widely expressed, with predominant levels found in the heart. It is an important component of the 3M complex, a complex required to regulate microtubule dynamics and genome integrity. The gene encoding this protein is implicated in 3M syndrome. Other names for this target antigen include obscurin-like protein 1 and obscurin like 1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
