Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

open access: yesFEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Structural features of human immunoglobulin G that determine isotype-specific differences in complement activation. [PDF]

open access: yes, 1993
Although very similar in sequence, the four subclasses of human immunoglobulin G (IgG) differ markedly in their ability to activate complement. Glu318-Lys320-Lys322 has been identified as a key binding motif for the first component of complement, C1q ...

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

open access: yes, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

Complement Activation by Trichophyton rubrum

open access: yesJournal of Investigative Dermatology, 1983
The role of complement in infections by dermatophytes is unknown. Therefore we evaluated the ability of the dermatophyte Trichophyton rubrum to activate complement in vitro. Aliquots of human plasma that had been incubated with T. rubrum were examined for evidence of complement activation.

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

open access: yesFEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. [PDF]

open access: yes, 2018
Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined.
