Anti-glutamine rich 1 antibodies are used for the immunodetection of the protein encoded by the QRICH1 gene. In humans, the canonical protein has a reported length of 776 amino acid residues and a mass of 86.4 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. It is a reported transcriptional regulator that acts as a mediator of the integrated stress response (ISR) through transcriptional control of protein homeostasis under conditions of ER stress. The gene encoding this protein is implicated in Ververi-Brady syndrome. Other names for this target antigen include VERBRAS, transcriptional regulator QRICH1, glutamine-rich protein 1, and AB-DIP. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot, Immunocytochemistry, and Immunofluorescence are common applications for glutamine rich 1 antibodies.
