Cryo-EM structures of the BAF-Lamin A/C complex bound to nucleosomes
Nature CommunicationsBarrier-to-autointegration factor (BAF) associates with mitotic chromosomes and promotes nuclear envelope assembly by recruiting proteins, such as Lamins, required for the reconstruction of the nuclear envelope and lamina.

Cryo-EM structure of the deltaretroviral intasome in complex with the PP2A regulatory subunit B56γ
Nature Communications, 2020 Human T-cell lymphotropic virus type 1 (HTLV-1) is a pathogenic deltaretrovirus. Here the authors resolve the cryo-EM structure of the deltaretroviral intasome in complex with the human host PP2A regulatory subunit.

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome
FEBS Letters, EarlyView.In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

Core nucleosomes are refractory to lentiviral DNA integration
Nature CommunicationsHIV-1 and other lentiviruses hijack the cellular chromatin-binding protein LEDGF/p75 to facilitate integration into active transcription units. However, the mechanism of chromatin engagement by lentiviral intasomes and the structural role of LEDGF/p75 in

Recruitment of Oct4 protein to UV-damaged chromatin in embryonic stem cells. [PDF]
, 2011 BACKGROUND: Oct4 is a specific marker of embryonic stem cell (ESC) pluripotency. However, little is known regarding how Oct4 responds to DNA damage. Here, we investigated whether Oct4 recognizes damaged chromatin in mouse ESCs stably expressing GFP-Oct4.

Open Biology, 2021 Histone H1s or the linker histones are a family of dynamic chromatin compacting proteins that are essential for higher-order chromatin organization. These highly positively charged proteins were previously thought to function solely as repressors of ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Essentiality of CENP-A Depends on Its Binding Mode to HJURP
Cell Reports, 2020 Summary: CENP-A incorporation is critical for centromere specification and is mediated by the chaperone HJURP. The CENP-A-targeting domain (CATD) of CENP-A specifically binds to HJURP, and this binding is conserved. However, the binding interface of CENP-

Identification and validation of transcription factors that regulate chromatin dynamics [PDF]
, 2012 Gene expression has to be tightly regulated during all cellular processes. During embryonic development differentiating cells loose their developmental potential and acquire specific functions by activating lineage-specific genes.
