Coactivator condensation at super-enhancers links phase separation and gene control

BR Sabari, A Dall'Agnese, A Boija, IA Klein, EL Coffey… - Science, 2018 - science.org
INTRODUCTION Mammalian genes that play prominent roles in healthy and diseased cellular
states are often controlled by special DNA elements called super-enhancers (SEs). SEs …

[PDF][PDF] Transcription factors activate genes through the phase-separation capacity of their activation domains

A Boija, IA Klein, BR Sabari, A Dall'Agnese, EL Coffey… - Cell, 2018 - cell.com
Gene expression is controlled by transcription factors (TFs) that consist of DNA-binding
domains (DBDs) and activation domains (ADs). The DBDs have been well characterized, but …

Partitioning of cancer therapeutics in nuclear condensates

IA Klein, A Boija, LK Afeyan, SW Hawken, M Fan… - Science, 2020 - science.org
The nucleus contains diverse phase-separated condensates that compartmentalize and
concentrate biomolecules with distinct physicochemical properties. Here, we investigated …

[HTML][HTML] Modulating biomolecular condensates: a novel approach to drug discovery

DM Mitrea, M Mittasch, BF Gomes, IA Klein… - Nature Reviews Drug …, 2022 - nature.com
In the past decade, membraneless assemblies known as biomolecular condensates have
been reported to play key roles in many cellular functions by compartmentalizing specific …

[HTML][HTML] Translocation-capture sequencing reveals the extent and nature of chromosomal rearrangements in B lymphocytes

IA Klein, W Resch, M Jankovic, T Oliveira, A Yamane… - Cell, 2011 - cell.com
Chromosomal rearrangements, including translocations, require formation and joining of
DNA double strand breaks (DSBs). These events disrupt the integrity of the genome and are …

Rag mutations reveal robust alternative end joining

B Corneo, RL Wendland, L Deriano, X Cui, IA Klein… - Nature, 2007 - nature.com
Mammalian cells repair DNA double-strand breaks (DSBs) through either homologous
recombination or non-homologous end joining (NHEJ). V(D)J recombination, a cut-and-paste …

[PDF][PDF] Biomolecular condensates and cancer

A Boija, IA Klein, RA Young - Cancer cell, 2021 - cell.com
Malignant transformation is characterized by dysregulation of diverse cellular processes
that have been the subject of detailed genetic, biochemical, and structural studies, but only …

[PDF][PDF] Enhancer features that drive formation of transcriptional condensates

K Shrinivas, BR Sabari, EL Coffey, IA Klein, A Boija… - Molecular cell, 2019 - cell.com
Enhancers are DNA elements that are bound by transcription factors (TFs), which recruit
coactivators and the transcriptional machinery to genes. Phase-separated condensates of TFs …

[PDF][PDF] AID produces DNA double-strand breaks in non-Ig genes and mature B cell lymphomas with reciprocal chromosome translocations

…, J Camps, S Deroubaix, KM McBride, IA Klein… - Molecular cell, 2009 - cell.com
Cancer-initiating translocations such as those associated with lymphomas require the formation
of paired DNA double-strand breaks (DSBs). Activation-induced cytidine deaminase (AID…

[PDF][PDF] Regulation of DNA end joining, resection, and immunoglobulin class switch recombination by 53BP1

…, DF Robbiani, M Di Virgilio, SF Bunting, IA Klein… - Molecular cell, 2011 - cell.com
53BP1 is a DNA damage protein that forms phosphorylated H2AX (γ-H2AX) dependent foci
in a 1 Mb region surrounding DNA double-strand breaks (DSBs). In addition, 53BP1 …
