Research Backgrounds

Function:

May play a role in microtubule-mediated transport or vesicle function.

Promotes the formation of autophagic vesicles.

PTMs:

Cleaved by caspases downstream of the polyglutamine stretch. The resulting N-terminal fragments are cytotoxic and provokes apoptosis.

Forms with expanded polyglutamine expansion are specifically ubiquitinated by SYVN1, which promotes their proteasomal degradation.

Phosphorylation at Ser-1179 and Ser-1199 by CDK5 in response to DNA damage in nuclei of neurons protects neurons against polyglutamine expansion as well as DNA damage mediated toxicity.

Myristoylated at Gly-551, following proteolytic cleavage at Asp-550.

Subcellular Location:

Cytoplasm. Nucleus. Early endosome.
Note: The mutant Huntingtin protein colocalizes with AKAP8L in the nuclear matrix of Huntington disease neurons. Shuttles between cytoplasm and nucleus in a Ran GTPase-independent manner (PubMed:15654337). Recruits onto early endosomes in a Rab5- and HAP40-dependent fashion (PubMed:16476778).

Tissue Specificity:

Expressed 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.

Family&Domains:

The 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.

Belongs to the huntingtin family.
