WebApr 5, 2024 · In this regulatory mechanism, a transcription factor binds to the promoter of a gene target to modulate its expression. The causal interactions between the transcription factors and their target genes collectively can drive a biological process and are known as a gene regulatory network (GRN) (Marbach et al., 2012). At one level, biological cells can be thought of as "partially mixed bags" of biological chemicals – in the discussion of gene regulatory networks, these chemicals are mostly the messenger RNAs (mRNAs) and proteins that arise from gene expression. These mRNA and proteins interact with each other with various degrees of specificity. Some diffuse around the cell. Others are bound to cell membranes, interacting with molecules in the environment. Still others pass through cell me…
