DNA N6-methyladenine modification regulators (6mA regulators)

DNA N6-methyladenine (6mA) modification regulators are a class of proteins responsible for the dynamic addition (writers), removal (erasers), and recognition (readers) of the 6mA epigenetic mark on deoxyadenosine. While 6mA is a well-established epigenetic modification in prokaryotes, its role in eukaryotes has recently gained attention, particularly regarding its influence on gene expression and chromatin structure in human cancers (Xiao et al., 2018). Specific proteins such as Protein Phosphatase 1 Regulatory Subunit 3A (PPP1R3A) and Autophagy Related 3 (ATG3) have been identified in bioinformatic signatures as key regulators or correlates of 6mA dynamics in malignancies like colorectal cancer, where they are associated with tumor progression and patient prognosis (Li et al., 2021). These regulators often possess dual roles; for example, ATG3 is a critical E2-like enzyme in the autophagy pathway, while PPP1R3A regulates glycogen synthesis, suggesting that 6mA-mediated epigenetic control may be integrated with fundamental cellular metabolic and homeostatic processes (Xie et al., 2018). Targeting these regulators offers a novel therapeutic avenue for modulating oncogenic signaling, though the multi-functional nature of proteins like ATG3 and PPP1R3A presents significant challenges for achieving therapeutic specificity without disrupting vital cellular functions.
