Dmbx1 Gene Summary [Rat]
Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Predicted to be involved in brain development; developmental growth; and regulation of DNA-templated transcription. Predicted to act upstream of or within adult feeding behavior; adult locomotory behavior; and negative regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Predicted to be part of transcription regulator complex. Orthologous to human DMBX1 (diencephalon/mesencephalon homeobox 1). [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 Dmbx1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
