Cold-Shock Domains—Abundance, Structure, Properties, and Nucleic-Acid Binding

Nucleic acid binding and intracellular localization of unr, a protein with five cold shock domains

The unr gene was identified as a transcription unit located immediately upstream of N-ras in the genome of several mammalian species. While this genetic organization could be important for the transcriptional regulation of unr and N-ras, the function of the protein product of unr is unknown. unr is ubiquitously expressed and codes for an 85 kDa protein which is not closely related to previously...

A Novel Cold-Regulated Cold Shock Domain Containing Protein from Scallop Chlamys farreri with Nucleic Acid-Binding Activity

BACKGROUND The cold shock domain (CSD) containing proteins (CSDPs) are one group of the evolutionarily conserved nucleic acid-binding proteins widely distributed in bacteria, plants, animals, and involved in various cellular processes, including adaptation to low temperature, cellular growth, nutrient stress and stationary phase. METHODOLOGY The cDNA of a novel CSDP was cloned from Zhikong sc...

Nucleic acid binding and other biomedical properties of artificial oligolysines

In the present study, we report the interaction of an artificial oligolysine (referred to as AOL) realized in our laboratory with targets of biomedical importance. These included polyinosinic acid (poly rI) and its complex with polycytidylic acid (poly I:C), RNAs with well-known interferon-inducing ability, and double-stranded (ds) DNA. The ability of the peptide to bind both single-stranded po...

Crystal structure, nucleic-acid binding properties, and dimerization model of Pur-alpha

The hnRNP F protein: unique primary structure, nucleic acid-binding properties, and subcellular localization.

More than 20 different heterogeneous nuclear ribonucleoproteins (hnRNPs) are associated with pre-mRNAs in the nucleus of mammalian cells and these proteins appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. The arrangement of hnRNP proteins on pre-mRNAs is likely to be unique for each RNA and may be determined by the different RNA-binding preferences of ...
