The C-terminal zinc finger domain of Arabidopsis cold shock domain proteins is important for RNA chaperone activity during cold adaptation
Phytochemistry(2010)
Abstract
Domain swapping between the cold shock domain proteins (CSDPs) 1 and 2 from Arabidopsis thaliana demonstrates that a specific modular arrangement of the cold shock domain and the zinc finger domain establishes both RNA chaperone activity and nucleic acid-binding property of CSDPs; this, in turn, contributes to enhanced chilling tolerance in plants as well as in bacteria.
