Protein Information (annotations from UniProt)

Database IDHIV0003906
UniProt IDO75934
Primary gene name(s)BCAS2
Synonym gene name(s)DAM1
Protein namePre-mRNA-splicing factor SPF27
Protein functionComponent of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing. May have a scaffolding role in the spliceosome assembly as it contacts all other components of the core complex. The PRP19-CDC5L complex may also play a role in the response to DNA damage, DDR. {ECO:0000269|PubMed:24332808}.
Subcellular locationNucleus, nucleolus {ECO:0000269|PubMed:12169396, ECO:0000269|PubMed:12429849, ECO:0000269|PubMed:20176811}.
