Anti-TRESK2 antibodies are used in antigen-specific immunodetection in biological samples. The target TRESK2 is a known alias name of the protein potassium two pore domain channel subfamily K member 18, encoded by the KCNK18 gene in humans. This 384-amino acid residue protein is known to be involved in potassium ion transport and the transport of ions, among other biological processes. It is localized to the cell membrane of the cell and features N-glycosylated and phosphorylated post-translational modifications. In terms of tissue expression, it is notably expressed in dorsal root ganglion and trigeminal ganglion neurons.
