The study found that one function of Cwc2 is to stabilize U2-U6 snRNA helix I during splicing.
Title: Remodeling of U2-U6 snRNA helix I during pre-mRNA splicing by Prp16 and the NineTeen Complex protein Cwc2.
The S. cerevisiae Cwc2 protein functions prior to step 1 of splicing.
Title: Cwc2 and its human homologue RBM22 promote an active conformation of the spliceosome catalytic centre.
we report the 1.9 A (1 A=0.1 nm) X-ray structure of the Cwc2 core domain, which is both necessary and sufficient for RNA binding.
Title: Structure of the mRNA splicing complex component Cwc2: insights into RNA recognition.
Yeast cells depleted of Cwc2 accumulate pre-mRNA and display reduced levels of U1, U4, U5 and U6 snRNAs.
Title: The RNA binding protein Cwc2 interacts directly with the U6 snRNA to link the nineteen complex to the spliceosome during pre-mRNA splicing.

NP_010072.1

Member of the NineTeen Complex (NTC); this complex contains Prp19p and stabilizes U6 snRNA in catalytic forms of the spliceosome containing U2, U5, and U6 snRNAs; binds directly to U6 snRNA; similar to S. pombe Cwf2
