CC -!- FUNCTION: Involved in pre-mRNA splicing. As a component of the NTC
CC complex, associates to the spliceosome to mediate conformational
CC rearrangement or to stabilize the structure of the spliceosome after U4
CC snRNA dissociation, which leads to spliceosome maturation.
CC {ECO:0000269|PubMed:11018040, ECO:0000269|PubMed:11102353,
CC ECO:0000269|PubMed:11842115, ECO:0000269|PubMed:12871902}.
CC -!- SUBUNIT: Belongs to the NTC complex (or PRP19-associated complex),
CC composed of at least CEF1, CLF1, ISY1, NTC20, SNT309, SYF1, SYF2, and
CC PRP19. The NTC complex associates with the spliceosome after the
CC release of the U1 and U4 snRNAs and forms the CWC spliceosome
CC subcomplex (or CEF1-associated complex) reminiscent of a late-stage
CC spliceosome composed also of the U2, U5 and U6 snRNAs and at least
CC BUD13, BRR2, CDC40, CUS1, CWC2, CWC15, CWC21, CWC22, CWC23, CWC24,
CC CWC25, CWC27, ECM2, HSH155, IST3, LEA1, MSL1, PRP8, PRP9, PRP11, PRP21,
CC PRP22, PRP45, PRP46, SLU7, SMB1, SMD1, SMD2, SMD3, SMX2, SMX3, SNU114,
CC SPP2, RSE1 and YJU2. Interacts with CEF1, CLF1, ISY1, PRP46, and SYF1.
