Anti-IP3R1 antibodies enable researchers to detect and measure the IP3R1 antigen in biological samples. This target is a reported synonym of the ITPR1 gene, which encodes inositol 1,4,5-trisphosphate receptor type 1. This protein is known to function in the transport of ions and the apoptotic pathway, among other biological roles. The human version of IP3R1 has a canonical amino acid length of 2758 residues and a protein mass of 313.9 kilodaltons, although 8 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles, ER, and cytoplasm of cells and notably expressed in the hippocampus, cerebral cortex, cerebellum, and caudate. Other names for this target antigen include ACV, CLA4, and INSP3R1. Some IP3R1 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA and Western Blot are also common applications.
