unreferenced date October 2009 Regulome refers to the whole set of regulation components in a cell biology cell . Those components can be gene s, mRNA s, protein s, and metabolite s. The description includes the interplay of regulatory effects between these components, and their dependence on variables such as subcellular localization , Biological tissue tissue , developmental stage, and pathological state. Components One of the major players in cellular regulation are transcription factor s, proteins that regulate the expression of genes. Other proteins that bind to transcription factors to form transcriptional complex es might modify the activity of transcription factors, for example blocking their capacity to bind to a promotor biology promoter . Signaling pathway s are groups of proteins that produce an effect in a chain that transmit a signal from one part of the cell to another part, for example, linking the presence of substance at the exterior of the cell to the activation of the expression of a gene. Measuring High throughput technologies for the analysis of biological samples for example, DNA microarray s, proteomics analysis allow the measurement of thousands of biological components such as mRNAs, proteins, or metabolites. Chromatin immunoprecipitation of transcription factors can be used to map transcription factor binding sites in the genome. Such techniques allow researchers to study the effects of particular substances and or situations on a cellular sample at a genomic level for example, by addition of a drug, or by placing cells in a situation of stress . The information obtained allows parts of the regulome to be inferred. Modeling One of the objectives of systems biology is the modelization of biological processes using mathematics and computer simulation . The production of data from techniques of genomic analysis is not always amenable to interpretation mainly due to the complexity of the data and the large amount of data points.
