AT3G11410 — Arabidopsis thaliana

Summary

AT3G11410 (AHG3, also known as AtPP2CA) encodes a protein phosphatase 2C (PP2C) of the PPM-type phosphatase family, classified as EC 3.1.3.16. This gene is associated with negative regulation of anion channel activity, membrane polarization, multicellular organismal water homeostasis, and regulation of membrane potential. It is linked to downregulation of seed dormancy, release of seed from dormancy, upregulation of chlorophyll breakdown, and responses to carbon dioxide, humidity, water, and basic pH. AHG3 is also associated with glucose-mediated signaling, regulation of abscisic acid anabolism, and sodium transport. The protein localizes to the tonoplast, vacuole, cis-Golgi network membrane, ER membrane, and pollen tube. Associations with traits include leaf water potential, water stress response, turgor pressure, submergence tolerance, specific leaf area, leaf elongation rate, root branching, and sensitivity to alkali, magnesium, manganese, potassium, nitrogen, nitrate, and acid.
