Pknox2 Gene Summary [Rat]
Predicted to enable RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; actin filament binding activity; and actin monomer binding activity. Predicted to act upstream of or within regulation of transcription by RNA polymerase II. Predicted to be located in several cellular components, including cytoskeleton; intercellular bridge; and nucleoplasm. Human ortholog(s) of this gene implicated in alcohol dependence. Orthologous to human PKNOX2 (PBX/knotted 1 homeobox 2). [provided by Alliance of Genome Resources, Apr 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 Pknox2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
