Predicted to enable GTPase activity and U5 snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to act upstream of or within RNA splicing and mRNA processing. Located in nucleus. Is expressed in several structures, including brain; branchial arch; embryo ectoderm; extraembryonic component; and optic cup. Human ortholog(s) of this gene implicated in esophageal atresia and mandibulofacial dysostosis, Guion-Almeida type. Orthologous to human EFTUD2 (elongation factor Tu GTP binding domain containing 2).
