Htt Gene Summary [Rat]
Enables signaling receptor binding activity. Involved in several processes, including mRNA transport; microtubule depolymerization; and negative regulation of extrinsic apoptotic signaling pathway. Located in several cellular components, including neuronal cell body; neuronal ribonucleoprotein granule; and synaptic membrane. Used to study Huntington's disease. Biomarker of transient cerebral ischemia. Human ortholog(s) of this gene implicated in Huntington's disease and Parkinson's disease. Orthologous to human HTT (huntingtin).

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