Anti-GLIPR1L1 antibodies are used in the immunodetection of the protein GLIPR1 like 1. In humans, the canonical protein has a reported length of 242 amino acid residues and a mass of 27.2 kDa. Its subcellular localization is in the cytoplasmic vesicles, cell membrane, and is secreted. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the testis. A member of the CRISP protein family, GLIPR1L1 is known to be required for optimal fertilization at the stage of sperm-oocyte fusion, plays a role in optimizing acrosome function, the translocation of IZUMO1 during the acrosome reaction and the fertilization process. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include GLIPR1-like protein 1 and GLI pathogenesis related 1 like 1. GLIPR1L1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the GLIPR1L1 antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
