Hmx2 Gene Summary [Rat]
Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including inner ear morphogenesis; positive regulation of cell population proliferation; and positive regulation of mRNA splicing, via spliceosome. Predicted to be active in nucleus. Orthologous to human HMX2 (H6 family homeobox 2). [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 Hmx2 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
