2.A.49.2.13 Clh-3; Clc-3, Clh3, Clc3 of 1001 aas and 11 TMSs. Isoform a: Voltage-gated chloride channel (Rutledge et al. 2002; Denton et al. 2005).
Insensitive to depolarizing voltages; requires low
voltages for activation; insensitive to chloride levels but has a mild
sensitivity to low pH. Channel gating properties are conferred by the
cytoplasmic C-terminus (He et al. 2006).
Plays a role in egg laying by modulating hermaphrodite-specific neuron excitability and the ovulatory contractions of
gap-junction-coupled gonadal sheath cells (Branicky et al. 2014). When active, may prevent tubular formation of the excretory canals (Hisamoto et al. 2008). Activated during oocyte meiotic maturation and by membrane hyperpolarization and cell swelling (Denton et al. 2004). Inhibited by Zn2+ and to a lesser extent by Cd2+(Rutledge et al. 2001). Isoform b: Voltage-gated chloride channel sensitive to depolarizing conditioning voltages; requires stronger
voltages for activation and activation is slower, is inhibited by low
concentrations of chloride and is activated by low pH. Channel gating
properties are conferred by the cytoplasmic C-terminus (He et al. 2006).
