Abstract excerpt
The Polycomb gene was discovered 60 years ago as a mutation inducing a particular homeotic phenotype. Subsequent work showed that Polycomb is a general repressor of homeotic genes. Other genes with similar function were identified and named Polycomb group (PcG) genes, while trithorax group (trxG) genes were shown to counteract PcG-mediated repression of homeotic genes. We now know that PcG and trxG proteins are...
