    Summary
    Enables mRNA binding activity. Involved in regulation of alternative mRNA splicing, via spliceosome; regulation of mRNA 3'-end processing; and regulation of transcriptional start site selection at RNA polymerase II promoter. Located in chromatin and nuclear speck. Is expressed in several structures, including adult heart; anterior endoderm; anterior endoderm anlage; embryonic/larval midgut primordium; and ganglia. Human ortholog(s) of this gene implicated in acute myeloid leukemia; congestive heart failure; hepatocellular carcinoma; and myelodysplastic syndrome. Orthologous to several human genes including SRSF2 (serine and arginine rich splicing factor 2). [provided by Alliance of Genome Resources, Dec 2024]
