Pou3f4 Gene Summary [Mouse]
Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in cochlea morphogenesis and negative regulation of mesenchymal cell apoptotic process. Acts upstream of or within forebrain neuron differentiation; inner ear development; and sensory perception of sound. Predicted to be located in nucleoplasm. Is expressed in several structures, including brain; cranium; ear; embryo ectoderm; and foregut-midgut junction. Human ortholog(s) of this gene implicated in X-linked deafness 2. Orthologous to human POU3F4 (POU class 3 homeobox 4). [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 mouse Pou3f4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
