Predicted to enable several functions, including ATP-dependent protein binding activity; RNA helicase activity; and snRNA binding activity. Predicted to be involved in several processes, including RNA metabolic process; positive regulation of cell growth involved in cardiac muscle cell development; and positive regulation of macromolecule biosynthetic process. Predicted to act upstream of or within mRNA processing and mRNA transport. Located in nuclear speck. Is expressed in embryo. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Orthologous to human DDX39B (DExD-box helicase 39B). [provided by Alliance of Genome Resources, Apr 2022]
