ICln is a ubiquitously expressed multi-functional protein that plays a critical role in regulating volume decrease in cells after cellular swelling. In plants, ICln induces Cl- currents [1,4,5], thus regulating Cl- homoeostasis in eukaryotes [2,3]. Structurally, the fold resembles a pleckstrin homology fold, on of whose roles is to recruit and tether their host protein to the cell membrane; and although the surface charges of the ICln fold are not equivalent to those of the PH domain, ICln can be phosphorylated in vitro and the PH-nature of the domain may be the part involving it in the transposition from cytosol to cell membrane during cytotonic swelling [1].
