Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Core component of the spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. Thereby, plays an important role in the splicing of cellular pre-mRNAs. Most spliceosomal snRNPs contain a common set of Sm proteins snrpb, snrpd1, snrpd2, snrpd3, snrpe, snrpf and snrpg that assemble in an heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP. As part of the U7 snRNP it is involved in histone 3'-end processing By similarity.By similarity

Interactioni

Subunit structurei

U1 snRNP is for instance composed of the 7 core Sm proteins snrpb, snrpd1, snrpd2, snrpd3, snrpe, snrpf and snrpg that assemble in an heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP, and at least three U1 snRNP-specific proteins snrnp70/U1-70K, snrpa/U1-A and snrpc/U1-C. Component of the U11/U12 snRNPs that are part of the U12-type spliceosome. Component of the heptameric ring U7 snRNP complex, or U7 Sm protein core complex, at least composed of LSM10, LSM11, SNRPB, SNRPD3, SNRPE, SNRPF, SNRPG and U7 snRNA By similarity.By similarity
