The TAK ELISA kits listed below utilize specific antibodies for the plate-based assay of TAK in various samples. TAK is another term for the CDK9 gene, which encodes the protein, cyclin dependent kinase 9 in humans. It has been reported that TAK plays a role in cell proliferation and cytokine-mediated signaling pathways, among other functions. Structurally, the CDK9 protein is 372 amino acid residues in length and 42.8 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 ubiquitously expressed across many tissue types. This protein is known to be ubiquitinated, acetylated and phosphorylated. Other names for this target antigen include C-2k, C-2k, and CDC2L4.
