Gene Information

General description

Hexanucleotide (GGGGCC) repeat expansions in a noncoding region of C9ORF72 are the major genetic cause of FTD and ALS (c9FTD/ALS). The RNA structure of GGGGCC repeats renders these transcripts susceptible to an unconventional mechanism of translation—repeat associated non-ATG (RAN) translation. Translation of the GGGGCC-repeat in all reading frames would result in three dipeptide-repeat (DPR) proteins poly-(Gly-Ala), poly-(Gly-Pro) and poly-(Gly-Arg). poly-GA and poly-GP proteins are extremely hydrophobic and may form intracellular aggregates

Specificity

This antibody recognizes C9ORF72/C9RANT (poly-GR) and other proteins containing poly-GR sequence, such as the Epstein Barr virus protein EBNA2

Immunogen

Epitope: poly-GR
Linear peptide corresponding to Epstein-Barr Virus Nuclear Antigen 2 (ENBA2) containing GR repeat sequence.

Application

Detect C9ORF72/C9RANT (poly-GR) using this Anti-C9ORF72/C9RANT (poly-GR) antibody, clone 5A2 validated for use in western blotting & IHC.
Immunohistochemistry Analysis: A representative lot detected poly-GR inclusions from brain tissues of C9orf72 patients with C9ORF72 hexanucleotide expansion (Mori, K., et al. (2013). Science. 339(6125):1335-1338.).

Quality

Evaluated by Western Blotting using GST fusion proteins with 15 GA, GP, or GR repeats, as well as GST alone without any repeat sequence.

Western Blotting Analysis: 0.2 μg of this antibody detected 10 μg of GR-GST recombinant protein with 15 GR repeats.

Hexanucleotide repeat expansion in C9ORF72 (C9) is the most prevalent mutation among amyotrophic lateral sclerosis (ALS) patients. The patients carry over ~30 to hundreds or thousands of repeats translated to dipeptide repeats (DPRs) where poly-glycine-arginine (GR) and poly-proline-arginine (PR) are

Large expansions of hexanucleotide GGGGCC (G4C2) repeats (hundreds to thousands) in the first intron of the chromosome 9 open reading frame 72 (C9orf72) locus are the strongest known genetic factor associated with amyotrophic lateral sclerosis and frontotemporal lobar degeneration. Different

Repeat expansion mutations in the C9ORF72 gene are the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG translation of this expansion produces dipeptide repeat proteins (DRPs). The arginine containing DRPs, polyGR and polyPR

Suggested C9orf72 disease mechanisms for amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration include C9orf72 haploinsufficiency, G4C2/C4G2 RNA foci, and dipeptide repeat (DPR) proteins translated from the G4C2 expansion; however, the role of small expansions (e.g., 30-90 repeats) is unknown

A G4C2 hexanucleotide repeat expansion in the noncoding region of C9orf72 is the major genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis (c9FTD/ALS). Putative disease mechanisms underlying c9FTD/ALS include toxicity from sense G4C2 and antisense G2C4 repeat-containing RNA, and
