Pou4f1 Gene Summary [Mouse]
Enables several functions, including DNA binding activity; DNA-binding transcription factor activity, RNA polymerase II-specific; and GTPase binding activity. Involved in several processes, including cellular response to estradiol stimulus; nervous system development; and regulation of gene expression. Acts upstream of or within several processes, including nervous system development; proprioception involved in equilibrioception; and suckling behavior. Located in several cellular components, including chromatin; neuron projection; and nucleus. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including branchial arch mesenchyme; central nervous system; future brain; ganglia; and sensory organ. Orthologous to human POU4F1 (POU class 4 homeobox 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 mouse Pou4f1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
