Ddit3 Gene Summary [Rat]
Enables DNA-binding transcription factor activity and protein heterodimerization activity. Contributes to sequence-specific DNA binding activity. Involved in several processes, including luteolysis; positive regulation of autophagy in response to ER overload; and regulation of DNA-templated transcription. Located in nucleus. Part of CHOP-C/EBP complex. Biomarker of several diseases, including borna disease; brain ischemia; chronic obstructive pulmonary disease; pulmonary venoocclusive disease; and ureteral obstruction. Human ortholog(s) of this gene implicated in myxoid liposarcoma. Orthologous to human DDIT3 (DNA damage inducible transcript 3). [provided by Alliance of Genome Resources, Jul 2025]

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 Ddit3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
