Anti-GIV antibodies are used in antigen-specific immunodetection in biological samples. The target GIV is a known alias name of the protein coiled-coil domain containing 88A, encoded by the CCDC88A gene in humans. This 1871-amino acid residue protein is reported to be a bifunctional modulator of guanine nucleotide-binding proteins (G proteins). It is localized to the cell membrane, cytoplasmic vesicles, and cytoplasm of the cell and features phosphorylated post-translational modifications. In terms of tissue expression, it is ubiquitously expressed across many tissue types. Some GIV antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, ELISA is also a common application.
