Anti-GTSE1 antibodies are used in the immunodetection of the protein G2 and S-phase expressed 1. In humans, the canonical protein has a reported length of 720 amino acid residues and a mass of 76.6 kDa. Its subcellular localization is in the cytoplasm. GTSE1 is suspected to be involved in p53-induced cell cycle arrest in G2/M phase by interfering with microtubule rearrangements that are required to enter mitosis. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include G2 and S phase-expressed protein 1, Lnc_bc060912, protein B99 homolog, and B99. GTSE1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GTSE1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
