Enables pre-mRNA 3'-splice site binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be part of U2AF complex and spliceosomal complex. Is an ortholog of human U2AF1 (U2 small nuclear RNA auxiliary factor 1) and U2AF1L4 (U2 small nuclear RNA auxiliary factor 1 like 4).
Predicted to enable mRNA binding activity. Involved in alternative mRNA splicing, via spliceosome. Predicted to be located in nucleus. Predicted to be part of spliceosomal complex. Is an ortholog of human SF1 (splicing factor 1).
Predicted to enable RNA binding activity. Involved in embryo development. Predicted to be located in nuclear speck. Expressed in PVDL; PVDR; and gonad. Human ortholog(s) of this gene implicated in several diseases, including gastrointestinal system cancer (multiple); lung non-small cell carcinoma (multiple); and urinary system cancer (multiple). Is an ortholog of human SRSF1 (serine and arginine rich splicing factor 1).
