Anti-cementum protein 1 antibodies are used for the immunodetection of the protein encoded by the CEMP1 gene. In humans, the canonical protein has a reported length of 247 amino acid residues and a mass of 26 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is noted to be expressed by cementoblasts, a subpopulation of periodontal ligament cells and cells located around vessels in periodontium. It is believed to play a role in development of the periodontium which surrounds and supports the teeth by promoting the differentiation of multi-potent cells from the periodontal ligament into cementoblasts to form the cementum. Post-translational modifications have been described, including N-glycosylation and phosphorylation. Other names for this target antigen include cementoblastoma-derived protein 1 and cementum protein 23. Some cementum protein 1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
