Charles David Allis

Charles David Allis (March 22, 1951 – January 8, 2023) was an American molecular biologist, and the Joy and Jack Fishman Professor at the Rockefeller University. He was also the Head of the Laboratory of Chromatin Biology and Epigenetics, and a professor at the Tri-Institutional MD–PhD Program (the other two institutions being the Memorial Sloan Kettering Cancer Center and Weill Cornell Medicine).

Early life and education Allis was born and raised in Cincinnati, Ohio. His father was a city planner and his mother an elementary school teacher. He entered the University of Cincinnati in 1969, majoring in biology. He had his first experience of basic research in his senior (or fourth) year of Bachelor of Science. The experience attracted him to research, and he went to Indiana University Bloomington for graduate studies. He graduated with an MSc in 1975 and a PhD three years later, under the supervision of Anthony Mahowald.

Allis returned to the University of Rochester in 1995, and became the Marie Curran Wilson and Joseph Chamberlain Wilson Professor of Biology two years later. In 1998, Allis went to the Department of Biochemistry and Molecular Genetics at the University of Virginia School of Medicine. He joined the Rockefeller University in 2003 as the Joy and Jack Fishman Professor and Head of the Laboratory of Chromatin Biology and Epigenetics. Chromatin biology at the time was not a popular topic; nor was the use of ciliated organisms. This was the first time that histone acetyltransferases were connected to DNA transcription activation, verifying Vincent Allfrey's hypothesis in the 1960s that histone acetylation regulates transcription.

Following this seminal report, Allis continued studying histone acetylation, discovering more histone acetyltransferases, including TAF1 (part of the transcription factor TFIID needed to initiate transcription). Allis also branched off to researching histone phosphorylation and histone methylation. He linked histone phosphorylation to mitosis and mitogen stimulation, and established a synergistic relationship between histone phosphorylation and acetylation. He also determined the role of methylation at lysine 9 of histone H3, identified SET domain-containing proteins as histone methyltransferase, and found that histone ubiquitylation regulates histone methylation.

In 2000, Allis and Brian Strahl proposed the "histone code hypothesis", which states that DNA transcription is largely regulated by histone modifications. Later, Allis (together with Thomas Jenuwein) explicitly associated the histone code with epigenetics, and recognized the clinical significance of histone modifications, especially in cancers.

In more recent years, his attention turned to "oncohistones", which are histones with mutations that distort normal histone modifications, leading to cancers.
