    Summary
    Enables mRNA binding activity. Involved in RNA splicing and regulation of RNA metabolic process. Located in nucleus. Part of catalytic step 2 spliceosome and precatalytic spliceosome. Is expressed in several structures, including CNS glial cell; embryonic/larval midgut primordium; ganglia; head epidermis primordium; and imaginal disc. Orthologous to several human genes including SRSF7 (serine and arginine rich splicing factor 7). [provided by Alliance of Genome Resources, Dec 2024]
