Dhx9 Gene Summary [Mouse]
Enables regulatory region RNA binding activity. Involved in positive regulation of interleukin-18 production; pyroptotic inflammatory response; and regulation of defense response. Acts upstream of or within cellular response to heat and circadian rhythm. Located in nucleolus. Is expressed in several structures, including alimentary system; central nervous system; lung; salivary gland primordium; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 75. Orthologous to human DHX9 (DExH-box helicase 9).

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 mouse Dhx9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
