CNG18_ARATH | function | Cyclic nucleotide-gated ion channel required for directional pollen tube growth into the transmitting tract (PubMed:17726111, PubMed:26929345). Acts as a Ca(2+)-permeable divalent cation-selective channel inhibited by either lanthanum or gadolinium (PubMed:24380879). Regulated by CPK32 to mediate Ca(2+) transport across the plasma membrane in response to Ca(2+) oscillation (PubMed:24121288). |
CNG18_ARATH | similarity | Belongs to the cyclic nucleotide-gated cation channel (TC 1.A.1.5) family. |
CNG18_ARATH | subcellular location | focused at the cell perimeter of the growing pollen tube tip. |
CNG18_ARATH | tissue specificity | Expressed in pollen grains. Not detected in leaves, roots or root hairs. |
