Researchers analyzed protein interaction data generated at Prolexys Pharmaceuticals that identified more than 100
huntingtin interacting proteins (HIPs) and more than 2,000 proteins that interact with HIPs.
This abnormal binding causes more VCP accumulation on the mitochondria,» Nerve cells with VCP - mutant
huntingtin interacting inside them became dysfunctional and self - destructed.

Xin Qi, PhD, assistant professor of physiology and biophysics at Case Western Reserve University School of Medicine has been looking for proteins that
interact with mutant
huntingtin to better understand the initial steps of Huntington's disease progression.
The VCP inside mitochondria only
interacted with mutant, but not healthy
huntingtin protein.
The team identified the regions of VCP and mutant
huntingtin that were
interacting.
The researchers worked to identify ways to prevent VCP from heading to nerve cell mitochondria and
interacting with mutant
huntingtin protein once inside.
«The challenge that remains is if there are many proteins
interacting with the
huntingtin protein, we can not easily determine which are relevant for disease and which are not,» said Erich Wanker from Max Delbrück Center for Molecular Medicine and corresponding author of the study.

During translation, however, the RNA instructions for extra-long
huntingtin can also
interact with a helper complex (the assistant chef from our analogy).
Since the helper complex mostly
interacts with the extra-length
huntingtin instructions, interfering with it should reduce translation of the extra-long variety.
The Steffan laboratory is being funded by the Hereditary Disease Foundation to investigate how the
Huntingtin protein
interacts with the ubiquitin - tagged trash in order to scaffold it to the lysosome for degradation, and to figure out what kinds of trash may be cleaned up by
Huntingtin.
