RNA recognition motif (RRM) found in yeast pre-mRNA-splicing factor Cwc2 and similar proteins
This subfamily corresponds to the RRM of yeast protein Cwc2, also termed Complexed with CEF1 protein 2, or PRP19-associated complex protein 40 (Ntc40), or synthetic lethal with CLF1 protein 3, one of the components of the Prp19-associated complex [nineteen complex (NTC)] that can bind to RNA. NTC is composed of the scaffold protein Prp19 and a number of associated splicing factors, and plays a crucial role in intron removal during premature mRNA splicing in eukaryotes. Cwc2 functions as an RNA-binding protein that can bind both small nuclear RNAs (snRNAs) and pre-mRNA in vitro. It interacts directly with the U6 snRNA to link the NTC to the spliceosome during pre-mRNA splicing. In the N-terminal half, Cwc2 contains a CCCH-type zinc finger (ZnF domain), a RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and an intervening loop, also termed RNA-binding loop or RB loop, between ZnF and RRM, all of which are necessary and sufficient for RNA binding. The ZnF is also responsible for mediating protein-protein interaction. The C-terminal flexible region of Cwc2 interacts with the WD40 domain of Prp19.
