Dnmt3a Gene Summary [Rat]
Enables chromatin binding activity. Involved in several processes, including cellular response to ethanol; hepatocyte apoptotic process; and positive regulation of cellular response to hypoxia. Located in nucleus. Used to study lung carcinoma and middle cerebral artery infarction. Biomarker of congenital heart disease; hepatocellular carcinoma; and prostatitis. Human ortholog(s) of this gene implicated in Tatton-Brown-Rahman syndrome; hematologic cancer (multiple); and stomach cancer. Orthologous to human DNMT3A (DNA methyltransferase 3 alpha).

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 Dnmt3a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
