Anti-GPCPD1 antibodies are used in the immunodetection of the protein glycerophosphocholine phosphodiesterase 1. In humans, the canonical protein has a reported length of 672 amino acid residues and a mass of 76 kDa. Its subcellular localization is in the cytoplasm. It is found to be widely expressed, with highest expression in spinal chord. A member of the Glycerophosphoryl diester phosphodiesterase protein family, GPCPD1 is suspected to be involved in the negative regulation of skeletal muscle differentiation, independently of its glycerophosphocholine phosphodiesterase activity. Synonyms for this target antigen include endometrial differential 3, glycerophosphocholine phosphodiesterase GDE1 homolog, glycerophosphodiester phosphodiesterase 5, preimplantation protein 4, and glycerophosphocholine phosphodiesterase GPCPD1. GPCPD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some GPCPD1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
