Description
Function: Plays role in pre-mRNA splicing as core component of precatalytic, catalytic and postcatalytic spliceosomal complexes (PubMed:28502770, PubMed:28781166, PubMed:29361316, PubMed:30315277, PubMed:29360106, PubMed:29301961, PubMed:30728453, PubMed:30705154). Involved in spliceosome assembly, activation and disassembly. Mediates changes in the dynamic network of RNA-RNA interactions in the spliceosome. Catalyzes the ATP-dependent unwinding of U4/U6 RNA duplices, an essential step in the assembly of a catalytically active spliceosome.
Subcellular Location: Nucleus.
Tissue Specificity: Widely expressed.
Subunit Structure: Component of a core complex containing at least PRPF8, SNRNP200, EFTUD2 and SNRNP40. Component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes, building blocks of the spliceosome. Component of the U4/U6-U5 tri-snRNP complex composed of the U4, U6 and U5 snRNAs and at least PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, TXNL4A, SNRNP40, DDX23, CD2BP2, PPIH, SNU13, EFTUD2, SART1 and USP39 (PubMed:16723661, PubMed:8670905, PubMed:26912367). Component of precatalytic, catalytic and postcatalytic spliceosomal complexes (PubMed:11991638, PubMed:28502770, PubMed:28781166, PubMed:29361316, PubMed:30315277, PubMed:29360106, PubMed:29301961, PubMed:30728453, PubMed:30705154).
Similarity: Contains two helicase domains. The N-terminal helicase domain has catalytic activity by itself, contrary to the C-terminal helicase domain that may have a regulatory role and enhance the activity of the first helicase domain.Belongs to the helicase family. SKI2 subfamily
