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 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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp313J1712; FP793; RN; RNU2AF1; Splicing factor U2AF 35 kDa subunit; splicing factor U2AF 35 kDa subunit-like protein; splicing factor U2AF 35kDa subunit; U2 auxiliary factor 35 kDa subunit; U2 small nuclear ribonucleoprotein auxillary factor, 35-KD subunit; U2 small nuclear RNA auxiliary factor 1; U2 small nuclear RNA auxiliary factor 1 like 5; U2 small nuclear RNA auxiliary factor 1-like protein 5; U2 small nuclear RNA auxillary factor 1; U2 snRNP auxiliary factor small subunit; U2(RNU2) small nuclear RNA auxiliary factor 1; U2(RNU2) small nuclear RNA auxiliary factor binding protein; U2AF1; U2AF1L5; U2AF35; U2AFBP\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 35\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797599375529,"sku":"13705T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-13705t","provider":"Iright","version":"1.0","type":"link"}
