HPCA1_ARATH | function | Leucine-rich repeat receptor protein kinase that acts as sensor of extracellular hydrogen peroxide (PubMed:32076270). Required for intracellular calcium influx in response to extracellular hydrogen peroxide (PubMed:32076270). Mediates hydrogen peroxide-induced activation of calcium channels in guard cells and is required for stomatal closure (PubMed:32076270). |
HPCA1_ARATH | similarity | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. |
HPCA1_ARATH | tissue specificity | Widely expressed. |
