Automated description from the Alliance of Genome Resources (Release 7.0.0)
Predicted to enable RNA binding activity. Predicted to be involved in U2-type prespliceosome assembly. Predicted to act upstream of or within RNA splicing. Predicted to be located in nuclear speck. Predicted to be part of U2 snRNP; U2-type precatalytic spliceosome; and catalytic step 2 spliceosome. Is expressed in several structures, including central nervous system; hemolymphoid system; liver; muscle tissue; and sensory organ. Orthologous to human SF3A3 (splicing factor 3a subunit 3).
