Abstract

A double-stranded RNA binding factor (RBF), characterized as an inhibitor of PKR kinase in our previous study, was evaluated for its RNA binding specificities by RNA gel electrophoretic mobility shift analysis and membrane filter binding assay, RBF displayed affinities for a broad range of RNAs including viral RNAs and synthetic RNAs consiting of stem and loop structures. GC-rich RNA stem helices as short as 11 bp are suggested to represent the minimal binding motif for RBF. RBF binding to all the natural RNAs tested was reversible by poly(I): poly(C) addition, but E. coli 5S RNA was inefficient.
