Anti-Cathepsin F antibodies are used for the immunodetection of the protein encoded by the CTSF gene. In humans, the canonical protein has a reported length of 484 amino acid residues and a mass of 53.4 kDa. Its subcellular localization is in the lysosomes. A member of the Peptidase C1 protein family, it is reported to be a thiol protease, which is believed to participate in intracellular degradation and turnover of proteins. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Ceroid lipofuscinosis. Other names for this target antigen include CATSF and CLN13. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. A number of Cathepsin F antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
