KCO6_ARATH | developmental stage | In flowers, mainly observed in the stamina and pollen sacs (PubMed:31053658). In mature leaves, restricted to hydathodes (PubMed:31053658). |
KCO6_ARATH | function | Two-pore potassium channel modulating the proton motive force (pmf) necessary to convert photochemical energy into physiological functions. Mediates the potassium efflux from the thylakoid lumen required for the regulation of the transmembrane electrical potential, the enhancement of the pH gradient for ATP synthesis, the regulation of electron flow, and pH-mediated photoprotective responses. Requires calcium for channel activity. |
KCO6_ARATH | similarity | Belongs to the two pore domain potassium channel (TC 1.A.1.7) family. |
KCO6_ARATH | subcellular location | PubMed:24009357 shows a thylakoid location instead of the tonoplast location previously described. |
KCO6_ARATH | tissue specificity | Expressed in roots, cotyledons, stems, hypocotyls, leaves and flowers (PubMed:31053658). Detected in root tips and in mesophyll cells and guard cells of the leaves. |
