Hoxb4 Gene Summary [Mouse]
Enables DNA binding activity. Acts upstream of or within several processes, including embryonic skeletal system morphogenesis; hematopoietic or lymphoid organ development; and hemopoiesis. Predicted to be located in centrosome. Predicted to be active in nucleoplasm. Is expressed in several structures, including embryo mesenchyme; genitourinary system; gut; nervous system; and skin. Orthologous to human HOXB4 (homeobox B4). [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 Hoxb4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
