Anti-TMEM16D antibodies enable researchers to detect and measure the TMEM16D antigen in biological samples. This target is a reported synonym of the ANO4 gene, which encodes anoctamin 4. This protein is known to function in cellular localization, among other biological roles. The human version of TMEM16D has a canonical amino acid length of 955 residues and a protein mass of 111.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells. TMEM16D is a member of the Anoctamin protein family.
