Sf3a3 - splicing factor 3a, subunit 3

Predicted to enable RNA binding activity. Predicted to be involved in U2-type prespliceosome assembly. Predicted to be located in nuclear speck. Predicted to be part of U2 snRNP; U2-type precatalytic spliceosome; and catalytic step 2 spliceosome. Orthologous to human SF3A3 (splicing factor 3a subunit 3).
