Life has existed on Earth for most of the planet’s history, yet major gaps and unresolved questions remain about how it first arose persisted. Early posed numerous challenges life, including harsh fluctuating environments. Today, many organisms cope with such conditions by entering a reversible state reduced metabolic activity, phenomenon known as dormancy. This process protects inactive individuals minimizes risk extinction preserving information that stabilizes life-system dynamics. Here, we develop framework understanding dormancy early Earth, beginning primer theory its core criteria. We hypothesize dormancy-like mechanisms acting chemical precursors in prebiotic world may have facilitated origin life. Drawing evidence from phylogenetic reconstructions fossil record, demonstrate is prevalent across tree life throughout deep time. These observations lead us to consider might shaped nascent living systems buffering stochastic processes small populations, protecting against large-scale planetary disturbances, aiding dispersal patchy landscapes facilitating adaptive radiations.

NBR1 was discovered as an autophagy receptor not long after the first described vertebrate p62/SQSTM1. Since then, p62 has currently been mentioned in >10,000 papers on PubMed, while is <350 papers. Nonetheless, evolutionary analysis reveals that NBR1, and likely also selective autophagy, present already last eukaryotic common ancestor (LECA), appears early Metazoan lineage. Furthermore, yeast-selective receptors Atg19 Atg34 represent homologs. main plants do contain p62, most animal taxa both p62. Mechanistic studies are starting to shed light collaboration between mammalian autophagic degradation of protein aggregates (aggrephagy). Several domains involved cargo recognition, list known substrates for NBR1-mediated increasing. Lastly, roles human diseases such proteinopathies cancer emerging.
