Mnx1 Gene Summary [Rat]
Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and sequence-specific double-stranded DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in chromatin; cytosol; and nuclear lumen. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in Currarino syndrome. Orthologous to human MNX1 (motor neuron and pancreas 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 Mnx1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
