Npas1 Gene Summary [Rat]
Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and protein heterodimerization activity. Predicted to be involved in negative regulation of DNA-templated transcription and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within maternal behavior; negative regulation of transcription by RNA polymerase II; and startle response. Predicted to be located in nucleus. Orthologous to human NPAS1 (neuronal PAS domain protein 1). [provided by Alliance of Genome Resources, Apr 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 Npas1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
