abstract = {Changes in cell function occur by specific patterns of
intracellular Ca2+, activating Ca2+-sensitive proteins. The
anoctamin (TMEM16) protein family has Ca2+-dependent ion
channel activity, which provides transmembrane ion
transport, and/or Ca2+-dependent phosphatidyl-scramblase
activity. Using amino acid sequence analysis combined with
measurements of ion channel function, we clarified the so
far unknown Ano4 function as Ca2+-dependent, non-selective
monovalent cation channel; heterologous Ano4 expression in
HEK293 cells elicits Ca2+ activated conductance with weak
selectivity of K+ > Na+ > Li+. Endogenously
expressed Ca2+-dependent cation channels in the retinal
pigment epithelium were identified as Ano4 by KO
mouse-derived primary RPE cells and siRNA against Ano4.
Exchanging a negatively charged amino acid in the putative
pore region (AA702–855) into a positive one (E775K) turns
Ano4-elicited currents into Cl− currents evidencing its
importance for ion selectivity. The molecular identification
of Ano4 as a Ca2+-activated cation channel advances the
understanding of its role in Ca2+ signaling.},
