s), and proteins that regulate RNA stability and translation ( PABP, La, Hu). The RRM in heterodimeric splicing factor U2 snRNP auxiliary factor appears to have two RRM-like domains with specialised features for protein recognition. The motif also appears in a few single stranded DNA binding proteins. The typical RRM consists of four anti-parallel beta-strands and two alpha-helices arranged in a beta-alpha-beta-beta-alpha-beta fold with side chains that stack with RNA bases. A third helix is present during RNA binding in some cases. The RRM is reviewed in a number of publications.
