Abstract Hey reddit, Today, in the journal Science, you can find our paper which describes the function of TDP, an important protein in ALS the disease that the ice bucket challenge raised money for tl;dr: DNA is located in the nucleus of a cell. You can think of a nucleus as a library except that instead of having books neatly lined up on shelves, the books in a nucleus have all of their pages ripped out and thrown around randomly.
It is thought to function by complexing with unpolymerized actin in vivo.
Dissociation of the profilin-actin complex is caused by binding of phosphatidylinositol 4,5-bisphosphate to profilin. Theriot and Mitchison reviewed the multiple functions of profilin.
Chromosomes 1, 6, 13, and 17 were implicated. In addition, 5-prime and 3-prime untranslated regions were found to be conserved between humans and rodents, implying a functional role for these regions of the profilin gene.
By study of patients with deletions and by use of somatic cell hybrids containing a deleted chromosome 17, Kwiatkowski et al. They found that the gene indeed was deleted in some patients with MDLS but that other patients had smaller deletions not affecting the profilin locus.
Thus, a single allelic deletion of the profilin locus may contribute to the clinical phenotype of MDLS in some patients but does not play a major role in the essential phenotype.
In the mouse, Klingenspor et al. One mutation EG; The EG mutation Homozygotes were not viable; they died as early as the 2-cell stage, and no homozygous knockout blastocysts were detectable. However, heterozygous embryos had reduced survival during embryogenesis compared with wildtype.
Although weakly expressed in early embryos, profilin-2 could not compensate for lack of profilin Their results indicated that mouse profilin-1 is an essential protein that has dosage-dependent effects on cell division and survival during embryogenesis.
Moreover, TLR11 is required in vivo for parasite-induced IL12 production and optimal resistance to infection, thereby establishing a role for the receptor in host recognition of protozoan pathogens.
A single obligate carrier of the C71G variant did not develop disease, but she died before the average age of onset of this family All unaffected family members displayed the wildtype genotype.
This mutation was subsequently identified in 2 other families. In family 3, the mutation was detected in 3 other affected family members. A single unaffected member of the family whose age was in the mid-forties was found to be a mutation carrier. The average age of onset in this family was Haplotype analysis suggested that the C71G variant derives from a single ancestral mutation.
This mutation was not observed among 7, control samples 15, alleles.Animal models are necessary to investigate the pathogenic features underlying motor neuron degeneration and for therapeutic development in amyotrophic lateral sclerosis (ALS).

Project Details: from the objective in WP8 as ALS model is not available and knowledge with knowledge with wasting diseases and development in zebrafish. Similarly, knockdown of tdp43 or expression of mutant TDP43 in zebrafish embryos results in an axonal phenotype early in development, which is further evidenced in swimming deficits at 48 hpf.
While these results reflect an effect of mutant ALS proteins on developing MN axons, the transient expression in these models limits the amount of insight that can be gained regarding the mechanisms of progressive .

TARDBP is a predominantly nuclear RNA/DNA-binding protein that functions in RNA processing and metabolism, including RNA transcription, splicing, transport, and stability.
Following cell stress, TARDBP also localizes to cytoplasmic stress granules and may play a role in stress granule formation.
