[[http://www.uniprot.org/uniprot/RUXF_HUMAN RUXF_HUMAN]] Appears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Associated with snRNP U1, U2, U4/U6 and U5. [[http://www.uniprot.org/uniprot/RSMB_HUMAN RSMB_HUMAN]] Appears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Associated with snRNP U1, U2, U4/U6 and U5. May have a functional role in the pre-mRNA splicing or in snRNP structure. Binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner (By similarity). [[http://www.uniprot.org/uniprot/RUXE_HUMAN RUXE_HUMAN]] Appears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Associated with snRNP U1, U2, U4/U6 and U5. [[http://www.uniprot.org/uniprot/RU17_HUMAN RU17_HUMAN]] Mediates the splicing of pre-mRNA by binding to the loop I region of U1-snRNA. The truncated isoforms cannot bind U1-snRNA. [[http://www.uniprot.org/uniprot/SMD3_HUMAN SMD3_HUMAN]] Appears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner.<ref>PMID:11574479</ref> [[http://www.uniprot.org/uniprot/RUXG_HUMAN RUXG_HUMAN]] Appears to function in the U7 snRNP complex that is involved in histone 3'-end processing. Associated with snRNP U1, U2, U4/U6 and U5. [[http://www.uniprot.org/uniprot/SMD1_HUMAN SMD1_HUMAN]] May act as a charged protein scaffold to promote snRNP assembly or strengthen snRNP-snRNP interactions through nonspecific electrostatic contacts with RNA. [[http://www.uniprot.org/uniprot/RU1C_HUMAN RU1C_HUMAN]] Component of the U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. U1-C is directly involved in initial 5' splice-site recognition for both constitutive and regulated alternative splicing. The interaction with the 5' splice-site seems to precede base-pairing between the pre-mRNA and the U1 snRNA. Stimulates E complex formation by stabilizing the base pairing of the 5' end of the U1 snRNA and the 5' splice-site region.<ref>PMID:2136774</ref> <ref>PMID:1826349</ref> <ref>PMID:8798632</ref> [[http://www.uniprot.org/uniprot/SMD2_HUMAN SMD2_HUMAN]] Required for pre-mRNA splicing. Required for snRNP biogenesis (By similarity). | |||
