Function
function
Involved in pre-mRNA splicing by stabilizing the NTC (or PRP19-associated complex). As a component of the NTC complex, associates to the spliceosome to mediate conformational rearrangement or to stabilize the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation.
Miscellaneous
Present with 721 molecules/cell in log phase SD medium.

Interaction
Subunit
Belongs to the NTC complex (or PRP19-associated complex), composed of at least CEF1, CLF1, ISY1, NTC20, SNT309, SYF1, SYF2, and PRP19. The NTC complex associates with the spliceosome after the release of the U1 and U4 snRNAs and forms the CWC spliceosome subcomplex (or CEF1-associated complex) reminiscent of a late-stage spliceosome composed also of the U2, U5 and U6 snRNAs and at least BUD13, BUD31, BRR2, CDC40, CUS1, CWC2, CWC15, CWC21, CWC22, CWC23, CWC24, CWC25, CWC27, ECM2, HSH155, IST3, LEA1, MSL1, PRP8, PRP9, PRP11, PRP21, PRP22, PRP45, PRP46, SLU7, SMB1, SMD1, SMD2, SMD3, SMX2, SMX3, SNU114, SPP2, RSE1 and YJU2. Interacts with PRP19.
