The Runt Related Transcription Factor 3 ELISA kits listed below are analytical tools for measuring concentrations of Runt Related Transcription Factor 3 in various samples. Runt Related Transcription Factor 3 is an alternative name for the human RUNX3 gene, which encodes the protein, RUNX family transcription factor 3. It has been mentioned that Runt Related Transcription Factor 3 plays a role in the regulation of transcription and the regulation of cell differentiation, among other functions. Structurally, the RUNX3 protein is 415 amino acid residues in length and 44.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in gastric cancer tissues. This protein is known to be phosphorylated. Other names for this target antigen include AML2, CBFA3, and PEBP2aC. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
