Hoxb2 Gene Summary [Rat]
Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including central nervous system development; embryonic skeletal system morphogenesis; and regionalization. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human HOXB2 (homeobox B2). [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 rat Hoxb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
