Summary
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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
