The initial conceptualization of molecular assemblies proposes novel organizational units, termed 'molecular organs,' which are envisioned to arise from the interplay of non-covalent interactions and specific structural motifs. This paradigm shift suggests a more granular understanding of cellular function, extending beyond traditional organelle structures to include emergent properties at the molecular level, particularly in protein-protein interactions and organelle biogenesis [1].
