CC polypyrimidine tract of introns early during spliceosome assembly (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Forms a heterodimer with the U2AF small subunit.
CC -!- INTERACTION:
CC Q24562; Q94535: U2af38; NbExp=4; IntAct=EBI-165226, EBI-121011;
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- DEVELOPMENTAL STAGE: Present throughout development.
CC -!- SIMILARITY: Belongs to the splicing factor SR family. {ECO:0000305}.
