Ddx39b Gene Summary [Rat]
Predicted to enable several functions, including ATP hydrolysis activity; ATP-dependent protein binding activity; and RNA 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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ddx39b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
