U2af1 - U2 small nuclear ribonucleoprotein auxiliary factor (U2AF) 1

Enables RS domain binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to act upstream of or within RNA splicing and mRNA processing. Located in nuclear speck. Is expressed in several structures, including genitourinary system; gut; nervous system; sensory organ; and skeleton. Orthologous to human U2AF1 (U2 small nuclear RNA auxiliary factor 1).
