Recombinant Human HTT Protein, His-tagged

• Cat.No.: HTT-2263H
• Product Overview: Recombinant Human HTT Protein (Thr803-Phe941) with a N-His tag was expressed in E. coli.

Specification

• Description: Huntingtin is a disease gene linked to Huntington's disease, a neurodegenerative disorder characterized by loss of striatal neurons. This is thought to be caused by an expanded, unstable trinucleotide repeat in the huntingtin gene, which translates as a polyglutamine repeat in the protein product. A fairly broad range of trinucleotide repeats (9-35) has been identified in normal controls, and repeat numbers in excess of 40 have been described as pathological. The huntingtin locus is large, spanning 180 kb and consisting of 67 exons. The huntingtin gene is widely expressed and is required for normal development. It is expressed as 2 alternatively polyadenylated forms displaying different relative abundance in various fetal and adult tissues. The larger transcript is approximately 13.7 kb and is expressed predominantly in adult and fetal brain whereas the smaller transcript of approximately 10.3 kb is more widely expressed. The genetic defect leading to Huntington's disease may not necessarily eliminate transcription, but may confer a new property on the mRNA or alter the function of the protein. One candidate is the huntingtin-associated protein-1, highly expressed in brain, which has increased affinity for huntingtin protein with expanded polyglutamine repeats. This gene contains an upstream open reading frame in the 5' UTR that inhibits expression of the huntingtin gene product through translational repression.

Q&As

What diseases is HTT associated with?

HTT is associated with neurodegenerative diseases such as Huntington's disease, Parkinson's disease, and Alzheimer's disease.

How can animal models be used to study the function and disease mechanism of HTT protein?

Animal models carrying human mutant genes can be constructed using transgenic or gene editing technology to study the role of HTT protein in vivo and disease mechanisms. These animal models can be used to study the effects of HTT proteins on neuronal function, synaptic transmission, behavior, and more, as well as to evaluate the effects of potential therapeutic strategies.

What are the therapeutic strategies for HTT protein?

Therapeutic strategies for HTT protein include inhibiting its expression, reducing its activity, or changing its modification state. A number of small molecule inhibitors and gene therapy strategies targeting HTT proteins are currently being studied.

Is there a challenge in HTT protein research?

There are still some challenges in the research of HTT proteins, such as the need to better understand their structure and functional relationships, and develop more effective drugs or treatments. In addition, due to the complexity and individual differences of neurodegenerative diseases, therapeutic strategies targeting HTT proteins also need to be adapted and optimized according to individual conditions.

How does HTT protein interact with other proteins or signaling pathways?

HTT protein can interact with other proteins and signaling pathways. For example, HTT proteins can interact with transcription factors to affect gene transcription, and can also interact with signaling pathways such as MAPK (mitogen-activated protein kinase) to participate in cell proliferation and apoptosis.

How can HTT protein be used for disease diagnosis?

By measuring the expression level and modification status of HTT protein, it can be used to diagnose diseases such as Huntington's disease. At present, there are some detection methods for HTT protein, such as western blotting, immunohistochemistry, etc.
