Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human SF3B1 protein.
Background
Splicing factor 3b subunit 1 (SF3B1) is an integral component of the U2 small nuclear ribonucleoprotein (U2 snRNP) and plays an important role in the splicing of pre-mRNA that involves the removal of introns and the joining of exons to form mature mRNA (1-3). The assembly and proper recognition of splice sites are driven by sequences at the pre-mRNA intron-exon splice sites. The 5’ splice donor site is recognized by the U1 snRNP complex, while U2 snRNP binds to the 3’ splice site (branch point), ensuring the anchoring of the spliceosome machinery at the splice sites (3,4). Recent whole exome sequencing studies have demonstrated a high incidence of somatic mutations of SF3B1 in patients with various hematological malignancies such as chronic lymphocytic leukemia and myelodysplastic syndromes (2,3,5,6). Misregulation of pre-mRNA splicing arising from mutations of the spliceosome components such as SF3B1 is thought to contribute to changes in the expression patterns of key proteins that are involved in pathways such as cell cycle progression, cell death, and cancer metabolism (2,3).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
