The process of protein ubiquitination requires an enzymatic cascade that consists of a ubiquitin activating enzyme E1ubiquitin conjugating enzyme E2 and an E3 ubiquitin ligase E3. Not surprisingly, mutations in E3 ligase genes have been observed in multiple neurological conditions.

Of the E3 ligase genes identified, 51 were associated with an RND.

The lab is interested in the epigenetic regulation of cell functions, including determination of cell fates, maintenance of genetic integrity, regulation of gene expression, genomic imprinting, X-chromosome inactivation and meiotic sex chromosome inactivation, methods of assisted reproduction, the evolution of tissue-specific gene expression in. The fossil record for ancient vertebrates is composed of rarely occurring fragments from which it is often impossible to obtain genetic material.

Here, we provide an updated list of neurological disorders associated with E3 ligase gene disruption. We further highlight research in these neurological disorders and discuss the advanced technologies used to support these findings.

Introduction Protein ubiquitination is a posttranslational modification that involves the covalent tethering of a small 76 amino acid protein called ubiquitin to target proteins Hershko and Ciechanover, Ubiquitination mediates many cellular functions, which include signal transduction and the removal of proteins by the ubiquitin proteasome system UPS Hershko, The initiation of protein ubiquitination typically requires an ATP-dependent enzymatic cascade that is initiated with the priming of a ubiquitin onto a ubiquitin activating enzyme E1 and the transfer to a ubiquitin conjugating enzyme E2 Komander and Rape, ; Zheng and Shabek, Ubiquitin is then covalently attached to a lysine residue on the target protein by an E3 ubiquitin ligase E3 and this process can be repeated to create a series of ubiquitin chains Hershko and Ciechanover, Ubiquitin chains can take various forms in length and configuration.

The fate of these chains leads to multiple cellular functions, one of which provides a signal for the protein to undergo degradation by the UPS Swatek and Komander, ; Yau and Rape, Although there are only 2 E1 and E2 genes, there are over human E3 ligase genes whose diversity is accounted for by three different types of catalytic domains: HECT E3s on the other hand, contain a catalytic cysteine residue that can form a thioester bond directly with ubiquitin.

E3 ligases have been linked to neurological disorders that include neurodegeneration, neurodevelopmental disorders, and intellectual disability Hegde and Upadhya, ; Upadhyay et al.

Although neurological disorders encompass a large array of genetic defects, next-generation sequencing NGS has enabled researchers to identify constituents of the ubiquitin pathway, namely E3 ligases, as causative factors for neurological disease Krystal and State, ; McCarroll et al.

We speculated that recent advances in NGS resulted in a massive expansion of the list of E3 ligases mutated in neurological disease.

Thus, understanding how E3 ligase disruption is a causative factor for neurological disease may contribute to a strategy for therapeutic interventions for both CNDs and especially RNDs Upadhyay et al.

Jan 01,  · Chromosome 6 is a prophetic thriller that challenges the medical ethics of genetic manipulation and cloning in the jungles of equatorial Africa, where one mistake could bridge the gap between man and ape--and forever change the genetic map of our existence/5.

A genetic hybrid carries two different alleles of the same gene, where for instance one allele may code for a lighter coat colour than the other.
