Kdm4b Gene Summary [Rat]
Predicted to enable histone H3K36 demethylase activity and histone H3K9me2/H3K9me3 demethylase activity. Predicted to be involved in brain development; chromatin remodeling; and regulation of gene expression. Predicted to be located in cytosol; nucleoplasm; and pericentric heterochromatin. Predicted to be active in chromatin and nucleus. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 65; breast cancer; colorectal cancer; malignant peripheral nerve sheath tumor; and stomach cancer. Orthologous to human KDM4B (lysine demethylase 4B). [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 Kdm4b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
