Anti-SQT1 antibodies are protein reagents that detect specific antigens. The SQT1 antigen is another term for the human protein potassium voltage-gated channel subfamily H member 2, encoded by the KCNH2 gene. The protein is known to function in the regulation of transcription, among other biological roles. Canonically, it has an amino acid length of 1159 residues and a mass of 126.7 kilodaltons. Its subcellular localization is in the cell membrane and it is reported to be highly expressed in the heart and brain. The SQT1 protein is a member of the Potassium channel protein family. Other alias names for SQT1 include ERG-1, ERG1, and H-ERG. A number of SQT1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
