Protein: Chloride channel protein CLC-e (Q8GX93)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Voltage-gated thylakoid chloride (Cl) channel/transporter involved in chloride homeostasis after transition from light to dark. Influences chloroplast ultrastructure and subsequent photosynthetic electron transport. During photosynthetic response on transition from dark to low light, involved in a sequential mechanism of adaptation; VCCN1 and CLCe first trigger the activation of photoprotection, which is later down-regulated by KEA3 to a low steady state, while adjusting electron transport. Regulates photosynthesis by a pH-independent mechanism likely involving Cl(-) homeostasis
Subcellular location: Membrane; Multi-pass membrane protein
