Anti-REEP4 antibodies are used in the immunodetection of the protein receptor accessory protein 4. In humans, the canonical protein has a reported length of 257 amino acid residues and a mass of 29.4 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in circumvallate papillae and testis. A member of the DP1 protein family, REEP4 is known to be a microtubule-binding protein required to ensure proper cell division and nuclear envelope reassembly by sequestering the endoplasmic reticulum away from chromosomes during mitosis. Synonyms for this target antigen include receptor expression-enhancing protein 4. REEP4 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Western Blot is a widely used application for the REEP4 antibodies listed below. In addition, ELISA is also a common application.
