Chloroplast bestrophin homologue of 410 aas and 4 or 5 TMSs, VCCN1. Plants adjust photosynthetic light utilization by controlling electron transport and photoprotective mechanisms, and this involves the proton motive force (PMF) across the thylakoid membrane. VCCN1 is a voltage-dependent Cl- channel which localizes to the thylakoid membrane and fine-tunes the PMF by anion influx into the lumen during illumination, adjusting electron transport and photoprotective mechanisms (Herdean et al. 2016). The activity of AtVCCN1 accelerates the activation of photoprotective mechanisms on sudden shifts to high light. Thus, AtVCCN1 acts as an early component in the rapid adjustment of photosynthesis in variable light intensities.
