Sim1 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 regulation of transcription by RNA polymerase II and ureteric bud development. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be located in nucleus. Human ortholog(s) of this gene implicated in obesity. Orthologous to human SIM1 (SIM bHLH transcription factor 1).

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 Sim1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
