HYPK, a Huntingtin interacting protein, reduces aggregates and apoptosis induced by N-terminal Huntingtin with 40 glutamines in Neuro2a cells and exhibits chaperone-like activity.

Abstract excerpt

Expansion of polymorphic glutamine (Q) numbers present at the protein Huntingtin (Htt) beyond 36Q results in its misfolding and aggregation, and the aggregates recruit several other proteins. Here we show that HYPK, initially identified as an Htt-interacting partner by yeast two-hybrid assay, physically interacts with N-terminal Htt in Neuro2A cells and alters the numbers and distribution of aggregates formed by...
