Odorant receptor (OR) gene choice is a paradigmatic exemplory case of stochastic regulation in which olfactory neurons choose one OR from 1,000 possibilities. instead is found to be enriched in H3K4me3. These epigenetic findings are consistent with a kinetic model of OR regulation and suggest a delicate tuning between activation and repression could underlie initiation.… Continue reading Odorant receptor (OR) gene choice is a paradigmatic exemplory case of
