Anti-Cla4 antibodies are used in antigen-specific immunodetection in biological samples. The target Cla4 is a known alias name of the protein inositol 1,4,5-trisphosphate receptor type 1, encoded by the ITPR1 gene in humans. This 2758-amino acid residue protein is reported to be an intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate. It is localized to the cytoplasmic vesicles, ER, and cytoplasm of the cell and features glycosylated, ubiquitinated, palmitoylated and phosphorylated post-translational modifications. In terms of tissue expression, it is widely expressed across many tissue types. Other synonyms for Cla4 include ACV and INSP3R1. Some Cla4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
