SF3B2 (Splicing Factor 3B Subunit 2) is a critical component of the spliceosome, a dynamic molecular machinery responsible for removing introns and joining exons during pre-mRNA splicing. It specifically resides within the SF3b complex, a submodule of the U2 small nuclear ribonucleoprotein (snRNP) that recognizes branch site sequences near intron-exon boundaries. SF3B2 plays a structural and functional role in stabilizing the spliceosome's interaction with pre-mRNA, ensuring accuracy in splice site selection. Mutations in SF3B2 or related splicing factors are frequently linked to diseases, notably myelodysplastic syndromes and certain cancers, where aberrant splicing promotes tumorigenesis. Recombinant human SF3B2 protein is typically expressed in vitro using bacterial or mammalian systems for functional studies. It serves as a vital tool to investigate spliceosome assembly mechanisms, dissect the impact of disease-associated mutations, and screen for therapeutic compounds targeting splicing defects. Recent studies also explore its potential role in modulating alternative splicing patterns implicated in cellular stress responses. As precision therapies focusing on RNA splicing gain traction, recombinant SF3B2 has become increasingly valuable for both basic research and drug development pipelines.
