Summary: Enables signaling receptor binding activity. Involved in several processes, including mRNA transport; microtubule depolymerization; and negative regulation of cysteine-type endopeptidase activity. Located in several cellular components, including neuronal cell body; neuronal ribonucleoprotein granule; and synaptic membrane. Used to study Huntington's disease. Biomarker of transient cerebral ischemia. Human ortholog(s) of this gene implicated in Huntington's disease and Parkinson's disease. Orthologous to human HTT (huntingtin).

We found that the protein is secreted via a late endosomal/lysosomal unconventional secretory pathway. Moreover, mHtt secretion can be reduced significantly by phosphatidylinositol 3-kinase and neutral sphingomyelinase inhibitors. Understanding and manipulating the secretion of mHtt is important because of its potentially harmful propagation in the brain.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
