“A Profound Change in Paradigm” — Scientists Uncover New Origin Story for Key Regulatory Gene

Posted by in category: futurism

The Polycomb repressive complex 2 (PRC2), initially identified in Drosophila several decades ago, was found to be a key controller of developmental genes. Subsequent research revealed that PRC2 alters chromatin structure to suppress the expression of specific genes.

This initial understanding of PRC2’s ancestral function — functioning primarily to control genes during development — was challenged when it was found to be active in unicellular organisms, in which no development takes place.
