A superfamily of proteins that contain the cold-shock domain.
Members of a family of cold-shock proteins (CSPs) are found throughout the eubacterial domain and appear to function as RNA-chaperones. They have been implicated in various cellular processes, including adaptation to low temperatures, cellular growth, nutrient stress and stationary phase. The discovery of a domain--the cold-shock domain--that shows strikingly high homology and similar RNA-binding properties to CSPs in a growing number of eukaryotic nucleic-acid-binding proteins suggests that these proteins have an ancient origin.
