These GRP1 ELISA kits are immunodetection tools for measuring the levels of GRP1 in biological samples. GRP1 is an alias of the human CYTH3 gene, which encodes the protein, cytohesin 3. The protein is reported to promote guanine-nucleotide exchange on ARF1 and ARF6. The CYTH3 protein is 400 amino acid residues in length and 46.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane and cytoplasm of the cell. Other names for this target antigen include ARNO3 and PSCD3.
