Phosphorylation of huntingtin at residue T3 is decreased in Huntington’s disease and modulates mutant huntingtin protein conformation [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance The findings in this manuscript report on the identification of a posttranslational modification in the huntingtin protein (phosphorylation on residue T3 in the N17 region of the protein), which can revert the conformational effects of the Huntington’s disease (HD) mutation itself on the huntingtin protein and inhibit its ...

The evolution of the huntingtin-associated protein 40 (HAP40) in conjunction with huntingtin [PDF]
BMC Evolutionary Biology, 2020 AbstractBackgroundThe huntingtin-associated protein 40 (HAP40) abundantly interacts with huntingtin (HTT), the protein that is altered in Huntington’s disease (HD). Therefore, we analysed the evolution of HAP40 and its interaction with HTT.ResultsWe found that in amniotes HAP40 is encoded by a single-exon gene, whereas in all other organisms it is ...

The Cellular and Subcellular Localization of Huntingtin-Associated Protein 1 (HAP1): Comparison with Huntingtin in Rat and Human [PDF]
The Journal of Neuroscience, 1998 The cellular and subcellular distribution of HAP1 was examined in rat brain by light and electron microscopic immunocytochemistry and subcellular fractionation. HAP1 localization was also determined in human postmortem tissue from control and Huntington’s disease (HD) cases by light microscopic immunocytochemistry.

Quantifying mutant huntingtin protein in human cerebrospinal fluid to support the development of huntingtin-lowering therapies. [PDF]
Sci Rep, 2023 AbstractHuntington’s disease (HD) is caused by a cytosine adenine guanine-repeat expansion in the huntingtin gene. This results in the production of toxic mutant huntingtin protein (mHTT), which has an elongated polyglutamine (polyQ) stretch near the protein’s N-terminal end.

Delineation of functional subdomains of Huntingtin protein and their interaction with HAP40. [PDF]
Structure, 2023 The huntingtin (HTT) protein plays critical roles in numerous cellular pathways by functioning as a scaffold for its many interaction partners and HTT knock out is embryonic lethal. Interrogation of HTT function is complicated by the large size of this protein so we studied a suite of structure-rationalized subdomains to investigate the structure ...

Effect of post-mortem delay on N-terminal huntingtin protein fragments in human control and Huntington disease brain lysates. [PDF]
PLoS ONE, 2017 Huntington disease is associated with elongation of a CAG repeat in the HTT gene that results in a mutant huntingtin protein. Several studies have implicated N-terminal huntingtin protein fragments in Huntington disease pathogenesis.

Cysteine String Protein Controls Two Routes of Export for Misfolded Huntingtin
Frontiers in Neuroscience, 2022 Extracellular vesicles (EVs) are secreted vesicles of diverse size and cargo that are implicated in the cell-to-cell transmission of disease-causing-proteins in several neurodegenerative diseases.

Huntingtin Interacting Proteins and Pathological Implications
International Journal of Molecular Sciences, 2023 Huntington’s disease (HD) is caused by an expansion of a CAG repeat in the gene that encodes the huntingtin protein (HTT). The exact function of HTT is still not fully understood, and previous studies have mainly focused on identifying proteins that interact with HTT to gain insights into its function.
