Hoxa3 Gene Summary [Mouse]
Enables DNA-binding transcription factor activity and HMG box domain binding activity. Acts upstream of or within several processes, including endocrine system development; regionalization; and skeletal system development. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; embryo mesenchyme; genitourinary system; gut; and nervous system. Used to study DiGeorge syndrome. Orthologous to human HOXA3 (homeobox A3). [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 Hoxa3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- RNA polymerase II transcription factor activity, sequence-specific DNA binding
- transcription regulator
- Domain of unknown function (DUF4074)
- protein domain specific binding
- protein binding
- transcription factor activity
- homeodomain
