Protein Information (annotations from UniProt)

Database IDHIV0002787
UniProt IDO75643
Primary gene name(s)SNRNP200
Synonym gene name(s)ASCC3L1, HELIC2, KIAA0788
Protein nameU5 small nuclear ribonucleoprotein 200 kDa helicase
Protein functionRNA helicase that plays an essential role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes. 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. {ECO:0000269|PubMed:16723661, ECO:0000269|PubMed:23045696, ECO:0000269|PubMed:8670905, ECO:0000269|PubMed:9539711}.
Subcellular locationNucleus {ECO:0000269|PubMed:9539711}.
