ERD2 — Oryza sativa Japonica

Summary

OsERD2 (also known as HSP70-2, OsHSC70-1, and several other synonyms) on rice chromosome 3 encodes a member of the Hsp70 family of heat shock proteins, characterized by an ATPase nucleotide-binding domain and a peptide-binding domain, and is annotated as an ATP-dependent protein folding chaperone. The gene is associated with a wide range of molecular functions including calcium-dependent phospholipid binding, DXP-synthase activity, preprotein binding, and Hsp90 binding. It is linked to biological processes such as protein denaturation, cell glucose homeostasis, response to humidity, cytosol-to-ER transport, RuBisCO assembly, and upregulation of defense response to oomycetes. Associations with agronomically important traits include grain shape, grain width and length, biomass yield, photosynthetic ability, carotenoid content, leaf water potential, and responses to salt, temperature, and chilling. The gene product localizes to multiple cellular compartments including the ER chaperone complex, mitochondrial outer membrane, and thylakoid lumen.
