Foxa3 Gene Summary [Mouse]
Enables sequence-specific DNA binding activity. Involved in regulation of transcription by RNA polymerase II and spermatogenesis. Acts upstream of or within several processes, including hematopoietic stem cell homeostasis; intracellular glucose homeostasis; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including brain; embryo mesenchyme; genitourinary system; gut; and skeleton. Orthologous to human FOXA3 (forkhead box A3).

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 Foxa3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
