| Function: | |
Pre-mRNA processing factor involved in disassembly of spliceosomes after the release of mature mRNA. In cooperation with TFIP11 seem to be involved in the transition of the U2, U5 and U6 snRNP-containing IL complex to the snRNP-free IS complex leading to efficient debranching and turnover of excised introns. {ECO:0000269|PubMed:19103666}. |

| Catalytic activity: | |
Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13; Evidence={ECO:0000269|PubMed:19432882}; |
| Subunit: | |
Interacts with SSB/La (PubMed:12458796). Component of the U11/U12 snRNPs that are part of the U12-type spliceosome (PubMed:15146077). Identified in the Intron Large (IL) complex, a post- mRNA release spliceosomal complex containing the excised intron, U2, U5 and U6 snRNPs, and splicing factors; the association may be transient. Interacts with TFIP11; indicative for a recruitment to the IL complex (PubMed:19103666). Interacts with GPATCH2 (PubMed:19432882). {ECO:0000269|PubMed:12458796, ECO:0000269|PubMed:15146077, ECO:0000269|PubMed:19103666, ECO:0000269|PubMed:19432882}. |
