Predicted to enable GTPase activity and U5 snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in cytosol. Predicted to be part of U2-type catalytic step 2 spliceosome and U4/U6 x U5 tri-snRNP complex. Human ortholog(s) of this gene implicated in several diseases, including esophageal atresia; hepatitis B; and mandibulofacial dysostosis, Guion-Almeida type. Is an ortholog of human EFTUD2 (elongation factor Tu GTP binding domain containing 2).
