Irx2 Gene Summary [Rat]
Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including negative regulation of transcription by RNA polymerase II; neuron differentiation; and proximal/distal pattern formation involved in nephron development. Predicted to be active in nucleus. Orthologous to human IRX2 (iroquois homeobox 2). [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 Irx2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
