Anti-PPIL1 antibodies are used in the immunodetection of the protein peptidylprolyl isomerase like 1. In humans, the canonical protein has a reported length of 166 amino acid residues and a mass of 18.2 kDa. Its subcellular localization is in the nucleus. It is found to be widely expressed, with the most abundant expression in the heart and skeletal muscle. A member of the Cyclophilin-type PPIase protein family, PPIL1 is known to be involved in pre-mRNA splicing as component of the spliceosome. The PPIL1 gene has been associated with the disease, Pontocerebellar hypoplasia. Synonyms for this target antigen include CYPL1, PCH14, PPIase, hCyPX, peptidyl-prolyl cis-trans isomerase-like 1, and CGI-124. PPIL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PPIL1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
