Hmbox1 Gene Summary [Rat]
Predicted to enable double-stranded telomeric DNA binding activity; identical protein binding activity; and sequence-specific double-stranded DNA binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II; telomere maintenance via telomerase; and telomere-telomerase complex assembly. Predicted to be located in several cellular components, including centrosome; chromosome, telomeric region; and nuclear body. Predicted to be active in nucleus. Orthologous to human HMBOX1 (homeobox containing 1). [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 Hmbox1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
