Hoxb3 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 several processes, including angiogenesis; embryonic skeletal system morphogenesis; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including hemopoiesis; nervous system development; and thyroid gland development. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human HOXB3 (homeobox B3). [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 Hoxb3 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 regulatory region sequence-specific binding transcriptional activator activity
  • RNA polymerase II transcription factor activity, sequence-specific DNA binding
  • transcription regulator
  • Domain of unknown function (DUF4074)
  • double-stranded DNA binding
  • nucleic acid binding
  • homeolike domain
  • sequence-specific DNA binding
