- Huntingtin protein and protein fragments; 293T cells; Mouse cortex tissue; Endogenous Huntingtin lysates, with or without caspase activity.
Human HTT caspase cleavage sites generate fragment-specific forms of the protein. Caspase-3/7 has been shown to generate cleavage sites at animo acids 513 and 552. Caspase-2 cleaves at amino acid 552 and caspase-6 at amino acid 586.

FunctionMay play a role in microtubule-mediated transport or vesicle function.
Tissue specificityExpressed in the brain cortex (at protein level). Widely expressed with the highest level of expression in the brain (nerve fibers, varicosities, and nerve endings). In the brain, the regions where it can be mainly found are the cerebellar cortex, the neocortex, the striatum, and the hippocampal formation.
Involvement in diseaseDefects in HTT are the cause of Huntington disease (HD) [MIM:143100]. HD is an autosomal dominant neurodegenerative disorder characterized by involuntary movements (chorea), general motor impairment, psychiatric disorders and dementia. Onset of the disease occurs usually in the third or fourth decade of life and symptoms progressively worsen leading to death in 10 to 20 years. Onset and clinical course depend on the degree of poly-Gln repeat expansion, longer expansions resulting in earlier onset and more severe clinical manifestations. HD affects 1 in 10,000 individuals of European origin. Neuropathology of Huntington disease displays a distinctive pattern with loss of neurons, especially in the caudate and putamen (striatum).
Sequence similaritiesBelongs to the huntingtin family.
Contains 10 HEAT repeats.
DomainThe N-terminal Gln-rich and Pro-rich domain has great conformational flexibility and is likely to exist in a fluctuating equilibrium of alpha-helical, random coil, and extended conformations.
modificationsCleaved by apopain downstream of the polyglutamine stretch. The resulting N-terminal fragment is cytotoxic and provokes apoptosis.
Forms with expanded polyglutamine expansion are specifically ubiquitinated by SYVN1, which promotes their proteasomal degradation.
Cellular localizationCytoplasm. Nucleus. The mutant Huntingtin protein colocalizes with AKAP8L in the nuclear matrix of Huntington's disease neurons.

Lanes 1-5 are 293Tcells expressing the full length Htt protein and treated with the various caspases. Lanes 6-9 are 293T overexpressing the different Htt fragments to demonstrate the antibody’s specificity to that neo-epitope. Probed with N-terminal pan-Huntingtin antibody or (bottom panel) neoepitope specific rabbit polyclonal antibody.
