    Background

    U2 small nuclear RNA auxiliary factor 1 (U2AF1) is the small (35 kDa) subunit of the U2 auxiliary factor (U2AF) that plays an essential role in the splicing of pre-mRNA to generate functional mRNA transcripts. U2AF1 forms a heterodimer with the large (65 kDa) U2AF2 subunit to create the U2 auxiliary factor that recognizes the 3' splice site and facilitates spliceosome assembly (1-3). Research studies indicate that U2AF1 binds to the 3'-splice site consensus AG dinucleotide at the intron-exon boundary while U2AF2 recognizes and binds the polyprimidine tract upstream of the 3’ splice site. These two steps ensure accurate spliceosome assembly at splice sites (4-6). Mutations in the corresponding U2AF1 gene are associated with a type of hematopoietic stem cell disorder known as myelodysplastic syndrome (MDS), which can be characterized by low blood counts, anemia, and enhanced acute myeloid leukemia risk (7-9). Somatic U2AF1 mutations frequently affect highly conserved zinc finger protein regions that result in defective pre-mRNA splicing of genes involved in cell cycle progression and RNA processing pathways, contributing to MDS pathogenesis (7,10).
