Structure and RNA binding of Nab3
Original language description
Besides mRNA, RNA polymerase II also transcribes a subset of small nuclear and small nucleoar RNAs, and a class of intergenic and anti-sense RNAs. Termination of these transcripts requires the nuclear pre-mRNA down- regulation (Nrd)1 and the nuclear polyadenylated RNA-binding (Nab)3 proteins, and the RNA helicase Sen1. In this so-called nonpoly(A) termination pathway, the RNA-binding proteins, Nrd1 and Nab3, recognize Nrd1- and Nab3-binding sites which is an initial step in the termination and subsequent processing or degradation of these transcripts. Recent studies identified sequence motives for Nrd1 and Nab3, as the signals that direct termination and exosome-TRAMP trimming/degradation of nonpolyadenylated transcripts. It was shown that the RNA-recognition motif (RRM) of Nrd1 and Nab3 bind to the GUA[A/G] and UCUU sequences, respectively.
