Gene : KCO6 A. thaliana

DB identifier  ? AT4G18160 Secondary Identifier  ? locus:2117681
Name  ? Ca2 activated outward rectifying K channel 6 Brief Description  Ca2 activated outward rectifying K channel 6
TAIR Computational Description  Ca2+ activated outward rectifying K+ channel 6;(source:Araport11)
TAIR Curator Summary  Encodes AtTPK3 (KCO6), a member of the Arabidopsis thaliana K+ channel family of AtTPK/KCO proteins. AtTPK3 is found in the thylakoid stromal lamellae. May form homomeric ion channels in vivo. It modulates the partitioning of the proton motive force (pmf) between the delta psi and delta pH in chloroplasts in vivo at physiological light intensities. Vacuolar K+-conducting TPC1 and TPK1/TPK3 channels act in concert to provide for Ca2+- and voltageinduced electrical excitability to the central organelle of plant cells.
TAIR Short Description  Ca2+ activated outward rectifying K+ channel 6
TAIR Aliases  ATKCO6, ATTPK3, KCO6, TPK3

Type Comment Proteins
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.
