Anti-TASK-2 antibodies enable researchers to detect and measure the TASK-2 antigen in biological samples. This target is a reported synonym of the KCNK5 gene, which encodes potassium two pore domain channel subfamily K member 5. This protein is known to function in potassium ion transport and the transport of ions, among other biological roles. The human version of TASK-2 has a canonical amino acid length of 499 residues and a protein mass of 55.1 kilodaltons. It is reported to be localized in the membrane of cells. Other names for this target antigen include K2p5.1, KCNK5b, and TASK-2.
