Predicted to enable several functions, including ATP-dependent protein binding activity; RNA helicase activity; and snRNA binding activity. Involved in several processes, including positive regulation of cell growth involved in cardiac muscle cell development; positive regulation of macromolecule biosynthetic process; and positive regulation of vascular associated smooth muscle cell proliferation. Located in nuclear matrix. Part of protein-containing complex. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Orthologous to human DDX39B (DExD-box helicase 39B).
