Target Background

Component of the C9orf72-SMCR8 complex, a complex that has guanine nucleotide exchange factor (GEF) activity and regulates autophagy. In the complex, C9orf72 and SMCR8 probably constitute the catalytic subunits that promote the exchange of GDP to GTP, converting inactive GDP-bound RAB8A and RAB39B into their active GTP-bound form, thereby promoting autophagosome maturation. The C9orf72-SMCR8 complex also acts as a regulator of autophagy initiation by interacting with the ATG1/ULK1 kinase complex and modulating its protein kinase activity. Positively regulates initiation of autophagy by regulating the RAB1A-dependent trafficking of the ATG1/ULK1 kinase complex to the phagophore which leads to autophagosome formation. Acts as a regulator of mTORC1 signaling by promoting phosphorylation of mTORC1 substrates. Plays a role in endosomal trafficking. May be involved in regulating the maturation of phagosomes to lysosomes. Regulates actin dynamics in motor neurons by inhibiting the GTP-binding activity of ARF6, leading to ARF6 inactivation. This reduces the activity of the LIMK1 and LIMK2 kinases which are responsible for phosphorylation and inactivation of cofilin, leading to cofilin activation. Positively regulates axon extension and axon growth cone size in spinal motor neurons. Plays a role within the hematopoietic system in restricting inflammation and the development of autoimmunity.; Regulates stress granule assembly in response to cellular stress.; Does not play a role in regulation of stress granule assembly in response to cellular stress.

  1. Review: Drosophila has been widely used to model G4C2 repeat RNA and dipeptide repeat protein toxicity. Overexpression of disease molecules in flies has revealed important molecular insights. These have been validated and further explored in human neurons differentiated from induced pluripotent stem cells (iPSCs), a disease-relevant model in which expanded G4C2 repeats are expressed in their native molecular context.

  4. Results found that in sodium or potassium salt solutions, single-stranded d(C2G4)n within C9orf72 gene fold to form G-quadruplexes. Especially under slightly acidic conditions, d(C2G4)n oligonucleotides fold to form a distinctive higher order structure whose most striking feature is an "inverted" circular dichroism spectrum, which is distinguishable from the spectrum of the left handed DNA double-helix, Z-DNA.

  19. Mutations in the footprinted region of Nup54 polymers blocked both polymerization and binding by the toxic proline:arginine poly-dipeptide suggesting that toxicity of the C9orf72 PRn poly-dipeptide results in part from its ability to lock the FG repeats of nuclear pore proteins in the polymerized state. PMID: 28069952
  20. DPR-mediated dysfunction of U2 snRNP could account for as much as approximately 44% of the mis-spliced cassette exons in C9ORF72 patient brains. PMID: 28614712

  32. Our study did not find any pathological C9ORF72 repeat expansions in two large groups of patients with disease and multiple system atrophy, suggesting that C9ORF72 expansions do not play a major role in the susceptibility to the wider spectrum of Parkinsonism. However, study identified a statistically significant association between number of repeats and age at onset in Parkinson's disease patients. PMID: 27473499
