anti-Huntingtin antibody [HDB4E10]
anti-Huntingtin antibody [HDB4E10] for IHC-Frozen sections,Immunoprecipitation,Western blot and Human,Mouse,Rabbit
Overview
| Product Description | Mouse Monoclonal antibody [HDB4E10] recognizes Huntingtin This antibody recognizes with an epitope corresponding to the HDB region (amino acids 1844 - 2131) of the huntingtin protein. Mouse anti Huntingtin antibody, clone HDB4E10 detects a ~350 kDa band on western blots but also detects smaller degradation products of huntingtin. The combined use of Mouse anti Huntingtin antibody, clones HDB4E10, HDC8A4 and HDA3E10 demonstrate that huntingtin is enriched in neuronal cells in the brain (Jones 1999). |

| Gene Symbol | HTT |
| Gene Full Name | huntingtin |
| Background | 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 in the number of trinucleotide repeats 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. [provided by RefSeq, Jul 2008] |
| Function | May play a role in microtubule-mediated transport or vesicle function. [UniProt] |
| Calculated MW | 348 kDa |
| PTM | Cleaved by apopain downstream of the polyglutamine stretch. The resulting N-terminal fragment is cytotoxic and provokes apoptosis. Forms with expanded polyglutamine expansion are specifically ubiquitinated by SYVN1, which promotes their proteasomal degradation. Phosphorylation at Ser-1179 and Ser-1199 by CDK5 in response to DNA damage in nuclei of neurons protects neurons against polyglutamine expansion as well as DNA damage mediated toxicity. |
