Anti-KCASH2 antibodies enable researchers to detect and measure the KCASH2 antigen in biological samples. This target is a reported synonym of the KCTD21 gene, which encodes potassium channel tetramerization domain containing 21. This protein is known to function in protein oligomerization and protein ubiquitination, among other biological roles. The human version of KCASH2 has a canonical amino acid length of 260 residues and a protein mass of 29.6 kilodaltons.
