Anti-CAPS antibodies are used in the immunodetection of the protein calcyphosine. In humans, the canonical protein has a reported length of 275 amino acid residues and a mass of 30.2 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the nasopharynx, fallopian tube, endometrium, and bronchus. CAPS is known to be involved with intracellular signal transduction. The CAPS marker can be used to identify Brain Ependymal Non-Neuronal Cells.* Synonyms for this target antigen include calcyphosin, calcyphosine 1, epididymis secretory sperm binding protein, thyroid protein p24, and CAPS1. CAPS gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some CAPS antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
