Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-SF3B1 antibody [EPR11986] (AB202926)

IHC image of SF3B1 staining in a section of formalin-fixed paraffin-embedded human colon adenocarcinoma*, performed on a Leica BONDTM. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab202926, 1/250 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Western blot - HRP Anti-SF3B1 antibody [EPR11986] (AB202926)

This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab202926 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.

Supplementary information

SF3B1 also known as Splicing Factor 3B subunit 1 plays an important role in the mRNA splicing process. This protein participates in the splicing machinery as part of the spliceosome contributing to the removal of introns from pre-mRNA. SF3B1 has a molecular weight of approximately 160 kDa. It is ubiquitously expressed yet shows a high level of activity in tissues with rapid cell division such as the bone marrow and lymphatic tissue reflecting its central involvement in gene expression regulation.
Biological function summary

SF3B1 is an essential component of the spliceosomal complex specifically the U2 snRNP component. It helps establish the branchpoint recognition complex ensuring accurate RNA splicing necessary for producing functional mRNA molecules. This process is important for the expression of diverse protein-coding genes affecting multiple aspects of cellular function and identity. The protein interacts with other spliceosomal proteins like SF3A and U2AF to guide the precise removal of non-coding sequences enabling proper translation into proteins.

Pathways

SF3B1 is involved in the mRNA processing pathway and influences the cell cycle pathway. During mRNA processing SF3B1 aids in assembling the spliceosome facilitating the excision of introns. The protein interacts with components like SF3B2 in coordinating splicing with other RNA processing events. In the cell cycle pathway SF3B1 indirectly affects gene expression and stability influencing cell cycle progression and serving as a regulatory node by modulating the splicing of key regulators active during cell division.

Several studies associate SF3B1 mutations with certain types of cancer including myelodysplastic syndrome and chronic lymphocytic leukemia. These mutations often result in aberrant splicing events leading to altered gene expression profiles that can promote tumorigenesis. Within these disease contexts SF3B1 abnormalities can influence interactions with related proteins like SRSF2 contributing to misregulated splicing patterns of genes that drive cancerous transformations and affect patient prognosis.

Target data

Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs (PubMed : 12234937, PubMed : 27720643, PubMed : 32494006, PubMed : 34822310, PubMed : 36104565). 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 : 32494006, PubMed : 34822310, PubMed : 36104565). Within the 17S U2 SnRNP complex, SF3B1 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 : 36104565). 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). Together with other U2 snRNP complex components may also play a role in the selective processing of microRNAs (miRNAs) from the long primary miRNA transcript, pri-miR-17-92 (By similarity).
