Anti-FAM111A antibodies are used in the immunodetection of the protein FAM111 trypsin like peptidase A. In humans, the canonical protein has a reported length of 611 amino acid residues and a mass of 70.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the FAM111 protein family, FAM111A is known to be involved with DNA damage pathways and DNA replication. Post-translational modifications have been described, including protein cleavage. The FAM111A gene has been associated with the disease, Kenny-Caffey syndrome. Synonyms for this target antigen include family with sequence similarity 111 member A, protein FAM111A, and serine protease FAM111A. FAM111A gene orthologs have been reported in the mouse, rat and chimpanzee species. Some FAM111A antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
