UniProt functional annotation for P08579

UniProt code: P08579.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28502770, PubMed:28781166, PubMed:28076346). Associated with sn-RNP U2, where it contributes to the binding of stem loop IV of U2 snRNA (PubMed:9716128). {ECO:0000269|PubMed:11991638, ECO:0000269|PubMed:28076346, ECO:0000269|PubMed:28502770, ECO:0000269|PubMed:28781166, ECO:0000269|PubMed:9716128}.
 
Subunit: Identified in the spliceosome B complex (PubMed:28781166). Identified in the spliceosome C complex (PubMed:11991638, PubMed:28502770, PubMed:28076346). Present in a spliceosome complex assembled in vitro, and composed of SNRPB2, HPRP8BP and CRNKL1 (PubMed:12084575). Contributes to the binding of stem loop IV of U2 snRNA with SNRPP1 (PubMed:9716128). {ECO:0000269|PubMed:11991638, ECO:0000269|PubMed:12084575, ECO:0000269|PubMed:28076346, ECO:0000269|PubMed:28502770, ECO:0000269|PubMed:28781166, ECO:0000269|PubMed:9716128}.
Subcellular location: Nucleus {ECO:0000269|PubMed:28076346, ECO:0000269|PubMed:28502770, ECO:0000269|PubMed:28781166}.
Miscellaneous: Patients with systemic lupus erythematosus produce antibodies which interact with snRNP proteins.
Similarity: Belongs to the RRM U1 A/B'' family. {ECO:0000305}.
