Hdac2 Gene Summary [Rat]
Enables several functions, including DNA-binding transcription factor binding activity; heat shock protein binding activity; and promoter-specific chromatin binding activity. Involved in several processes, including behavioral response to ethanol; positive regulation of cell differentiation; and regulation of macromolecule metabolic process. Located in chromatin. Used to study Peyronie's disease; alcohol use disorder; and anxiety disorder. Biomarker of anxiety disorder; bronchitis; chronic obstructive pulmonary disease (multiple); endometriosis; and fetal alcohol spectrum disorder. Human ortholog(s) of this gene implicated in stomach cancer. Orthologous to human HDAC2 (histone deacetylase 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 Hdac2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
