Abstract RNA-binding proteins play essential roles in the regulation of gene expression. Many have modular structures and combine relatively few common domains in various arrangements to recognize RNA sequences and/or structures. Recent progress in engineering the specificity of the PUF class RNA-binding proteins has shown that RNA-binding domains may be combined with various effector or functional domains to regulate the metabolism of targeted RNAs. Designer RNA-binding proteins with tailored sequence specificity will provide valuable tools for biochemical research as well as potential therapeutic applications. In this review, we discuss the suitability of various RNA-binding domains for engineering RNA-binding specificity, based on the structural basis for their recognition. We also compare various protein engineering and design methods applied to RNA-binding proteins, and discuss future applications of these proteins. © 2013 FEBS.
