Supplementary information

SF3B3 also known as SAP130 is a component of the splicing factor 3b complex vital for pre-mRNA processing. It is approximately 130 kDa in mass and prominently expressed across various tissue types including the liver lungs and heart. SF3B3 functions in the spliceosome a complex machinery essential for the removal of introns from pre-mRNA transcripts.
Biological function summary

SF3B3 participates in the assembly and stabilization of the functional spliceosomal complex. It is a part of the larger SF3b complex which is critical for recognizing the branch point sequence in RNA during splicing. This recognition influences the selection of splice sites and impacts the regulation of alternative splicing events. The SF3b complex works with the U2 small nuclear ribonucleoprotein (snRNP) during the splicing process to ensure accurate and efficient mRNA maturation.

Pathways

SF3B3 plays a significant role in the splicing pathway and impacts gene expression regulation through alternative splicing. It works alongside proteins such as SF3B1 and other splicing factors maintaining proper cellular function by influencing transcript variants. Another important pathway involving SF3B3 is RNA transport where it assists in the export of mature and correctly processed mRNA from the nucleus to the cytoplasm.

SF3B3 is closely linked to myelodysplastic syndromes and certain types of cancer such as breast cancer. Mutations or dysregulation of SF3B3 can result in aberrant splicing patterns contributing to tumorigenesis and disease progression. The protein is often studied along with SF3B1 as both are part of the splicing machinery and have been implicated in splicing-related genetic abnormalities that drive these disorders.

Target data

Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs (PubMed : 10490618, PubMed : 10882114, PubMed : 12234937, PubMed : 27720643, PubMed : 28781166, PubMed : 32494006, PubMed : 34822310). The 17S U2 SnRNP complex (1) directly participates in early spliceosome assembly and (2) mediates recognition of the intron branch site during pre-mRNA splicing by promoting the selection of the pre-mRNA branch-site adenosine, the nucleophile for the first step of splicing (PubMed : 12234937, PubMed : 32494006, PubMed : 34822310). Within the 17S U2 SnRNP complex, SF3B3 is part of the SF3B subcomplex, which is required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence in pre-mRNA (PubMed : 12234937, PubMed : 27720643). Sequence independent binding of SF3A and SF3B subcomplexes upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA (PubMed : 12234937). May also be involved in the assembly of the 'E' complex (PubMed : 10882114). Also acts as a component of the minor spliceosome, which is involved in the splicing of U12-type introns in pre-mRNAs (PubMed : 15146077, PubMed : 33509932).
