Anti-CWF19 like cell cycle control factor 1 antibodies are used for the immunodetection of the protein encoded by the CWF19L1 gene. In humans, the canonical protein has a reported length of 538 amino acid residues and a mass of 60.6 kDa. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in many brain regions, including cerebellum, thalamus and occipital, parietal and temporal lobes. A member of the CWF19 protein family, it is known to be involved with RNA splicing. The gene encoding this protein is implicated in Spinocerebellar ataxia. Other names for this target antigen include SCAR17, hDrn1, CWF19-like protein 1, CWF19 like 1, cell cycle control, CWF19-like 1 cell cycle control, and C19L1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
