These Qk ELISA kits are immunodetection tools for measuring the levels of Qk in biological samples. Qk is an alias of the human QKI gene, which encodes the protein, QKI, KH domain containing RNA binding. Notably, Qk is known to play a role in mRNA processing and the regulation of gene expression, among other functions. The QKI protein is 341 amino acid residues in length and 37.7 kilodaltons in mass. However, as many as 6 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 the frontal cortex of brain. This protein is known to be methylated and phosphorylated. Other names for this target antigen include Hqk and QK1. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
