CCDC94 is part of the spliceosome which catalyzes two sequential transesterification reactions, first the excision of the non-coding intron from pre-mRNA and then the ligation of the coding exons to form the mature mRNA. CCDC94 also plays a role in stabilizing the structure of the spliceosome catalytic core and docking of the branch helix into the active site, producing 5'-exon and lariat intron-3'-intermediates. CCDC94 may protect cells from TP53-dependent apoptosis upon dsDNA break damage through association with PRP19-CD5L complex.
