Small intranuclear proteins also participate in generating alternative splicing techniques of pre-mRNA and, by this mechanism, contribute to sexual differentiation in at least two species, Drosophila melanogaster and Caenorhabditis elegans….

…changes in these regulatory processing activities are associated with human disease and cancer. These findings emphasize the supraspliceosome as a multi-task master regulator of pre-mRNA processing in the cell nucleus.
…the initiator-tRNA species proposed to participate in SOS reside in the cell nucleus, are found associated with supraspliceosomes (Table 2c), and appear not to be charged with an amino acid .
Energy-dependent regulation of the supraspliceosome and RNA-mediated amino acid substitutions is charge-regulated and the change in the charge must be linked to fixation of the amino acid substitution in the organized genomes of all living genera before energy can be linked to biologically-based cause and effect via what is known to all serious scientists about how the physiology of reproduction must be linked to biodiversity.
The changes in the supraspiceosome must then be linked from chromosomal rearrangements to morphological and behavioral diversity.

Beyond defining the functions of CTCF in chromosome folding, these results provide new fundamental insights into the rules governing mammalian genome organization.
My summary: The rules integrate what is known about energy-dependent adenosine to inosine RNA editing. See: Divergent prebiotic synthesis of pyrimidine and 8-oxo-purine ribonucleotides
Prebiotic synthesis starts with the sun’s anti-entropic virucidal energy.
See: Common origins of RNA, protein and lipid precursors in a cyanosulfidic protometabolism
RNA biosynthesis is energy-dependent and an endogenous substrate appears to be the link from sunlight to protometabolism. By starting from protometabolism, it is easy to link the energy from the innate immune system to polycombic ecological adaptations in all living genera via the physiology of reproduction.

little is known about the mechanistic underpinnings of how differently composed Polycomb complexes instruct and maintain cell fate. Here we find that Mel18, also known as Pcgf2 and one of six Pcgf paralogs, uniquely regulates PRC1 to specify mesoderm cell fate in embryonic stem cells. Mechanistically, Mel18 functions as a classical Polycomb protein during early cardiac mesoderm differentiation by repressing pluripotency, lineage specification, late cardiac differentiation, and negative regulators of the BMP pathway. However, Mel18 also positively regulates expression of key mesoderm transcription factors, revealing an unexpected function of Mel18 in gene activation during cardiac differentiation. Taken together, our findings reveal that Mel18 is required to specify PRC1 function in both a context- and stage-specific manner.
The context- and stage-specific links from polycombic ecological adaptation are nutrient energy-dependent and the regulation of polycombic ecological adaptations is biophysically constrained by the pheromone-controlled physiology of reproduction in all living genera.

For contrast, see: Is inference the best way to explain the origin of consciousness?
- Excerpt: “On this view, a loss of consciousness occurs whenever our models lose their ‘thickness’ and become as ‘thin’ as a virus’s.”
Consciousness is energy dependent and biophysically constrained by the ability of organisms to find food and reproduce. Consciousness is manifested as increasing organismal complexity in the context of links from quantum consciousness to quantum souls.
The fact that it took only one journalist to expose all the others who have not asked the right questions about consciousness so that the questions could be answered in the context of what is known to all serious scientists about virus-driven energy theft and all pathology is revealed here, and in the first interview from the week before.
2. I just placed the essay on “Consciousness” into the context of “snake centric” evolution after scanning two published works by the author [Friston, Karl J.]
1) Top-Down Control of Visual Responses to Fear by the Amygdala http://www.jneurosci.org/content/33/44/17435.abstract
2) Bayesian inferences about the self (and others): A review http://www.sciencedirect.com/science/article/pii/S1053810014000105

“Science is the belief in the ignorance of experts” — Richard Feynman
Feynman supported the efforts of those who laugh at ‘experts,’ especially when the experts are not among the serious scientists who were forced to link ecological variation to energy-dependent ecological adaptation in the context of what is now known about how to link food energy-dependent changes from angstroms to ecosystems in all living genera via feedback loops and the pheromone-controlled physiology of reproduction.
In “The Pleasure of Finding Things Out,” (see pages 124 and 125 for a summary) Richard Feynman presciently predicted that the ability to see interactions at the level of atomic energy would link quantized energy from sunlight to photosynthesis and pattern recognition by biologists, who would then link quantum physics from chemistry to the growth and movement of all organisms on Earth.
1) The findings reveal similarities and differences with a recently published report on the IP3R using a completely different method called cryo-electron microscopy.
2) The team identified an amino acid sequence in the leaflet that is conserved in parasites, suggesting structural insights that may assist in drug discovery for these devastating conditions.
By identifying the amino acid sequence, they inadvertently linked natural selection for energy-dependent codon optimality to all biodiversity via the biophysically constrained physiology of reproduction in the context of hydrogen-atom transfer in DNA base pairs in solution.
