The JOS ELISA kits listed below are analytical tools for measuring concentrations of JOS in various samples. JOS is an alternative name for the human ATXN3 gene, which encodes the protein, ataxin 3. It has been mentioned that JOS plays a role in cytoskeleton organization and chemical synaptic transmission, among other functions. Structurally, the ATXN3 protein is 361 amino acid residues in length and 41.3 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be ubiquitinated. Other names for this target antigen include AT3 and ATX3. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
