Expression cloning revealed a chloride channel (I(Cln)) that we found to be fundamental for the regulatory volume decrease in a variety of cells. The chromosomal localization of the human I(Cln)-gene showed two loci, one at chromosome 11 in position q13.5-q14.1, termed CLNS1A, and a second one at chromosome 6 at position p12.1-q13, termed CLNS1B. In this study, we offer a detailed characterization of the CLNS1A gene and provide the exact position (6p12) and sequence data of CLNS1B, an intronless gene 91.3% homologous to the coding region of CLNS1A.
