    Name Na+ : K+ : 2Cl cotransporter (SLC12A1)
    Remark(s) large number of mutations are located at the C- terminus, which is an indication of the importance of this domain in SLC12A1 protein expression and function (C- terminally truncated proteins are not expressed at the cell surface of renal cells, because they are retained in the ER) (PMID: 19535327))
