RAG2 is composed of a "core" domain that is required for the recombination reaction and a C-terminal nonessential or "non-core" region.
Functional analysis of disease and phosphoinositide-binding mutations reveals novel intramolecular interactions within the non-core region and suggests that the PHD finger adopts two distinct states.
Recent evidence has emerged arguing that the non-core region plays a critical regulatory role in the recombination reaction, and mutations in this region have been identified in patients with immunodeficiencies.
At 1 bar the stability is higher for the core region (ΔG0=6.5(±2.0) kcal/mol) than for the non-core region (4.6(±1.3) kcal/mol), but at high pressure the stability is reversed due to a larger ΔV value of unfolding for the core region (90.0(±35.2) ml/mol) than that for the non-core region (57.4(±14.4) ml/mol), possibly due to an uneven distribution of cavities.
A genome-wide transcriptional non-core region, delineated by genes of markedly lower GC content, sparse gene density and inverted repeats, is broadly repressed following the switch.
Furthermore, the nrps7, pks5, and pks6 gene clusters are closely located in the non-core region, particularly the pks5 and pks6 clusters.
In previous studies each these modules was presumed to code for a non-core region of the large-subunit (LSU) rRNA [ 21].
Like other actinomycetes, the genome is divided into two large regions, with a core region thought to contain the majority of genes essential for survival, and a non-core region enriched for genes for conditionally adaptive functions [ 2, 14].
Recently, a novel "quasi-core" region, with typical core characteristics, was defined within the non-core region of the A. mediterranei U32 genome, along with the proposition of three discriminable criteria, including the gathering of essential genes, the discrepancy in coding density of orthologous genes and the co-linearity of the orthologs' order [ 24].
Basic is highly levered and its stock was beaten down when it announced plans in August to relocate assets and exit non-core regions.
Honig and Bedi (2012) also investigated this hypothesis in their study of conference papers, but they divided the world into "core" and "non-core" regions, arguing that nations which have a longer history of academic institutions would have lower instances of plagiarism than "non-core" regions, which were more recently institutionalized.
