Acquired 'Phase Separation' Underlies Aberrant Cell Fate Control?

Chromatin readers are important intermediaries linking epigenetic information and biological phenotypes. Many diseases are caused by mutations in epigenetic readers. Recently, a study by Wan et al. uncovered that cancer-associated mutations promote self-association of eleven-nineteen-leukemia protein (ENL), leading to abnormal condensates, elevated gene expression, and impaired cell fate determination.
