Human genome regulation.

In the early 90s, Manfred Eigen lectured at Hoffman-La Roche and explained that a gene of 1,000 base pairs has 10605 combinations. This number suggests that the Human Genome cannot be randomly created in time. In order to give human beings the power to control any disease including aging, we must, first, accept the definition that the Human Genome contains an infinite amount of information (nonlocal) that morphs into an infinite number of genes (local) as reflected in origami shapes and fractal structures. Based on this viewpoint, the Human Genome, which consists of 3 billion bps, is categorized into 2 parts. The expression (local) part consists of the 20,687 known protein-coding genes that occupy 2.94% of the Human Genome; whereas, the remaining 97% is referred to as the unknown creation (nonlocal) part. The 20,687 functional genes are developed through unknown processes and mechanisms within the creation part. We postulate that nature not only uses the 1,000 gene-regulating proteins (transcription factor) to regulate the 20,687 known genes, but also that a proportion of these genes are potentially involved in the unknown processes and mechanisms within the Human Genome's 97% creation part. From these 1,000 gene-regulating proteins, the zinc finger domains with 3 fingers recognize 9 base pairs that occur 10,000 times in the Human Genome. In addition, such domains identify specific 9 base pairs which vary under different conditions. Therefore, it is plausible that 3-finger-domains are involved in the unknown processes and mechanisms of the creation part. Further research is necessary to explore how and why nature uses small, 3-finger-domains. If we understand how nature uses these 3-finger-domains to regulate genes, then we might begin to comprehend how nature controls the unknown parts of the Human Genome. Since each single zinc finger binds to a variety of the 64 possible trinucleotide combinations, we can anticipate that a 3-finger-domain binds to numerous 9-base-pair sequences. When a zinc finger protein binds to numerous sequences, it is only active at the desired target locations; whereas, if the protein binds at off-target locations, then it is not active. In addition, when the protein is active at a target location, the binding must be reversible in a very timely manner to avoid over- or under-expression that lead to pathogenic side-effects. Although, if the natural process only guides and binds the protein to a targeted location and further prevents the domain from binding at off-target locations, then the process becomes too complex and inefficient for nature to control. So, why then, does nature rely on 3-finger-domains? We propose that 3-finger-domains are versatile and that the same domain can be used to bind in different conditions to other 9-base-pair sequences in order to execute diverse functions in both the 3% and the 97% sections of the Human Genome. In contrast, domains with 6 or more fingers are not versatile because such domains would bind to limited locations in the 3% section of the Human Genome. Moreover, an increased number of fingers in a domain decrease the control of the reversibility of the binding. In order to explain how nature controls 3-finger-domains, we should develop methods that distinguish between active target sequences and inactive off-target sequences. Out of the 262,144 combinations of a 9 base pair sequence, the active target sequences are those where a domain induces gene expression in an in-vivo model or a human cell based assay. A more practical approach would be to test each finger with the 64 trinucleotide combinations in order to determine active 9-base-pair sequences. Each of these identified active target sequences occur 10,000 times in the Human Genome. This vast quantity of sequences must be mapped. Then, the surrounding sequences should be analyzed to determine similarities, patterns, and structures that are clustered in certain areas in the Human Genome. David Bohm's theory states that nature is an infinite wholeness with an implicate order created neither randomly nor planned by outside forces. His theory supports our premise that the Human Genome infinitely creates from within itself. Genes instantaneously appear and nature directs their placement. Once we discover how these underlying processes and mechanisms operate such as how nature regulates 3 finger domains, then researchers can identify techniques to regulate the Human Genome.
