Genbank accession number
- Key message
- OsRZ2 complemented the cold sensitivity of BX04 Escherichia coli cells under low temperatures, and had DNA-melting activity and transcription anti-termination activity, thereby indicating that OsRZ2 possesses an RNA chaperone activity
- Ectopic expression of OsRZ2, but not OsRZ3, in cold-sensitive Arabidopsis grp7 knockout plants rescued the grp7 plants from cold and freezing damage, and OsRZ2 complemented the defect in mRNA export from the nucleus to the cytoplasm in grp7 mutant during cold stress
- Connection
- OsRZ2, OsRZ3, Zinc finger-containing glycine-rich RNA-binding protein in Oryza sativa has an RNA chaperone activity under cold stress conditions, Ectopic expression of OsRZ2, but not OsRZ3, in cold-sensitive Arabidopsis grp7 knockout plants rescued the grp7 plants from cold and freezing damage, and OsRZ2 complemented the defect in mRNA export from the nucleus to the cytoplasm in grp7 mutant during cold stress
- OsRZ1, OsRZ2, Structural features important for the RNA chaperone activity of zinc finger-containing glycine-rich RNA-binding proteins from wheat Triticum avestivum and rice Oryza sativa, Although the amino acid sequence similarity among wheat TaRZ2, wheat TaRZ3, and rice OsRZ1 was high, only TaRZ2 had RNA chaperone activity as evidenced by complementation ability in cold-sensitive Escherichia coli mutant cell under cold stress and in vivo and in vitro nucleic acid-melting activity
