Target data The SMN complex catalyzes the assembly of small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome, and thereby plays an important role in the splicing of cellular pre-mRNAs (PubMed : 16857593, PubMed : 18984161, PubMed : 20513430, PubMed : 33963192). Most spliceosomal snRNPs contain a common set of Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG that assemble in a heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP (Sm core). In the cytosol, the Sm proteins SNRPD1, SNRPD2, SNRPE, SNRPF and SNRPG are trapped in an inactive 6S pICln-Sm complex by the chaperone CLNS1A that controls the assembly of the core snRNP (PubMed : 18984161). To assemble core snRNPs, the SMN complex accepts the trapped 5Sm proteins from CLNS1A forming an intermediate (PubMed : 18984161). Binding of snRNA inside 5Sm ultimately triggers eviction of the SMN complex, thereby allowing binding of SNRPD3 and SNRPB to complete assembly of the core snRNP. Within the SMN complex, GEMIN5 recognizes and delivers the small nuclear RNAs (snRNAs) to the SMN complex (PubMed : 11714716, PubMed : 16314521, PubMed : 16857593, PubMed : 19377484, PubMed : 19750007, PubMed : 20513430, PubMed : 27834343, PubMed : 27881600, PubMed : 27881601). Binds to the 7-methylguanosine cap of RNA molecules (PubMed : 19750007, PubMed : 27834343, PubMed : 27881600, PubMed : 27881601, Ref.27). Binds to the 3'-UTR of SMN1 mRNA and regulates its translation; does not affect mRNA stability (PubMed : 25911097). May play a role in the regulation of protein synthesis via its interaction with ribosomes (PubMed : 27507887). See full target information Gem-associated protein 5
