ANN1 — Arabidopsis thaliana

Summary

AT1G35720, also known as ANN1, ANNAT1 or Oxy5, encodes an annexin family protein in Arabidopsis thaliana. The product possesses calcium-dependent phospholipid binding, peroxidase activity, RNA folding chaperone activity, and binds calcium, copper, zinc, ATP, and mRNA. ANN1 is associated with freezing tolerance, heat stress tolerance, cold-induced calcium signaling, phototropism, lateral root formation, nematode susceptibility, uranium accumulation and uptake, and reactive oxygen species regulation. The protein localises to the root hair tip, apoplast, thylakoid, chloroplast stroma, vacuole, Golgi, plasmodesmata, and membrane. ANN1 is linked to leaf water potential, leaf length and shape, petiole length, sugar and protein content, jasmonic acid content, nitrate transport, and responses to salt, osmotic, water, high and low temperature, and abscisic acid stress. It is also connected to calcium homeostasis, potassium transport, root hair development, immunity against Botrytis cinerea, systemic defense against herbivory, and small RNA loading into extracellular vesicles.
