Anti-KRS1 antibodies enable researchers to detect and measure the KRS1 antigen in biological samples. This target is a reported synonym of the STK3 gene, which encodes serine/threonine kinase 3. This protein is known to function in the apoptotic pathway and the Wnt signaling pathway, among other biological roles. The human version of KRS1 has a canonical amino acid length of 491 residues and a protein mass of 56.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. This target antigen may also be known as MST2. Western Blot is the most common application for the KRS1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
