Abstract

This chapter details how RNA-binding proteins package RNA, protect RNA, organize RNA, and prepare RNA for post-transcriptional processes. It describes different kinds of RNA-binding and auxiliary domains that enable RNA-binding proteins to bind RNA in a versatile way. It also mentions hnRNP proteins, which are the first RNA-binding proteins to be studied in some detail. The chapter discusses the hnRNP proteins that package premRNA. These are involved in multiple post-transcriptional processes. Also, hnRNP proteins remain bound to messenger RNA in the cytoplasm in mRNP particles. The chapter covers the RNA recognition motif, which is a sequence of amino acids or a specific arrangement of secondary structure.
