Hoxb13 Gene Summary [Rat]
Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and methyl-CpG binding activity. Involved in prostate gland development and response to testosterone. Predicted to be located in nucleoplasm. Predicted to be part of transcription regulator complex. Human ortholog(s) of this gene implicated in ductal carcinoma in situ and renal cell carcinoma. Orthologous to human HOXB13 (homeobox B13). [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 Hoxb13 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
