Anti-cytohesin 1 antibodies are used for the immunodetection of the protein encoded by the CYTH1 gene. In humans, the canonical protein has a reported length of 398 amino acid residues and a mass of 46.4 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is ubiquitously expressed across many tissue types. It is reported to promote guanine-nucleotide exchange on ARF1, ARF5 and ARF6. Post-translational modifications have been described, including ubiquitination. Other names for this target antigen include D17S811E, PSCD1, SEC7, PH, SEC7 and coiled-coil domain-containing protein 1, SEC7 homolog B2-1, and B2-1. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of cytohesin 1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
