Anti-GLYCTK antibodies are used in the immunodetection of the protein glycerate kinase. In humans, the canonical protein has a reported length of 523 amino acid residues and a mass of 55.3 kDa. Its subcellular localization is in the mitochondria and cytoplasm. Up to 7 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Glycerate kinase type-2 protein family, GLYCTK is known to be involved with protein phosphorylation. The GLYCTK gene has been associated with the disease, D-glyceric aciduria. Synonyms for this target antigen include HBeAg binding protein 4 and HBeAg-binding protein 2. GLYCTK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the GLYCTK antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
