| Background Information | SAP130, also known as Splicing factor 3B subunit 3, is part of the RNA splicing machinery. It is expressed by the Sf3b3 gene and encodes subunit 3 of the splicing factor 3b protein complex. As a component of this protein complex, it is associated with U2 snRNP and recruited to prespliceosomal complexes. Splicing factor 3b along with splicing factor 3a and a 12S RNA, form the U2 small nuclear ribonucleoprotein complex (U2 snRNP). In pre-mRNA’s, the splicing factor 3b/3a complex binds upstream of intron branch sites possibly anchoring the U2 snRNP to the pre-mRNA. SAP130 is also a component of the STAGA (SPT3-TAF(II)31-GCN5L acetylase) transcription coactivator-HAT (histone acetyltransferase) complex, and the TFTC (TATA-binding-protein-free TAF(II)-containing complex). These complexes are believed to function in chromatin modification, transcription, splicing, and DNA repair. |

| UniProt Summary | FUNCTION: Subunit of the splicing factor SF3B required for A complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the E complex. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron by similarity. SUBUNIT STRUCTURE: Identified in the spliceosome C complex, at least composed of AQR, ASCC3L1, C19orf29, CDC40, CDC5L, CRNKL1, DDX23, DDX41, DDX48, DDX5, DGCR14, DHX35, DHX38, DHX8, EFTUD2, FRG1, GPATC1, HNRPA1, HNRPA2B1, HNRPA3, HNRPC, HNRPF, HNRPH1, HNRPK, HNRPM, HNRPR, HNRPU, KIAA1160, KIAA1604, LSM2, LSM3, MAGOH, MORG1, PABPC1, PLRG1, PNN, PPIE, PPIL1, PPIL3, PPWD1, PRPF19, PRPF4B, PRPF6, PRPF8, RALY, RBM22, RBM8A, RBMX, SART1, SF3A1, SF3A2, SF3A3, SF3B1, SF3B2, SF3B3, SFRS1, SKIV2L2, SNRPA1, SNRPB, SNRPB2, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF, SNRPG, SNW1, SRRM1, SRRM2, SYF2, SYNCRIP, TFIP11, THOC4, U2AF1, WDR57, XAB2 and ZCCHC8. Component of splicing factor SF3B which is composed of at least eight subunits; SF3B1/SAP155/SF3B155, SF3B2/SAP145/SF3B145, SF3B3/SAP130/SF3B130, SF3B4/SAP49/SF3B49, SF3B14A, PHF5A/SF3B14B, SF3B10 and SF3B125. SF3B associates with the splicing factor SF3A and a 12S RNA unit to form the U2 small nuclear ribonucleoproteins complex (U2 snRNP). Interaction between SF3B3 and SF3B1 is tighter than the interaction between SF3B3 and SF3B2. Associates with the STAGA transcription coactivator-HAT complex. Interacts with SUPT3H by similarity. SUBCELLULAR LOCATION: Nucleus by similarity. SEQUENCE SIMILARITIES: Belongs to the RSE1 family. |
