The QK3 ELISA kits listed below utilize specific antibodies for the plate-based assay of QK3 in various samples. QK3 is another term for the QKI gene, which encodes the protein, QKI, KH domain containing RNA binding in humans. It has been reported that QK3 plays a role in mRNA processing and the regulation of gene expression, among other functions. Structurally, 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, QK, and QK1.
