Genetic Reporter System for Positioning of Proteins at the Bacterial Pole
Spatial organization within bacteria is fundamental to many cellular processes, although the basic mechanisms underlying localization of proteins to specific sites within bacteria are poorly understood. The study of protein ...
Activation of PAD4 in NET formation.
Peptidylarginine deiminases, or PADs, convert arginine residues to the non-ribosomally encoded amino acid citrulline in a variety of protein substrates. PAD4 is expressed in granulocytes and is essential for the formation ...
Peptidylarginine deiminase 2-catalyzed histone H3 arginine 26 citrullination facilitates estrogen receptor alpha target gene activation
Cofactors for estrogen receptor α (ERα) can modulate gene activity by posttranslationally modifying histone tails at target promoters. Here, we found that stimulation of ERα-positive cells with 17β-estradiol (E2) promotes ...
Inhibition of PAD4 activity is sufficient to disrupt mouse and human NET formation.
PAD4 has been strongly implicated in the pathogenesis of autoimmune, cardiovascular and oncological diseases through clinical genetics and gene disruption in mice. New selective PAD4 inhibitors binding a calcium-deficient ...
Citrulination unravels stem cells
Maintenance of the pluripotent stem cell state is regulated by the post-translational modification of histones. The discovery that citrullination of the linker histone H1 is critical to this
A novel role for protein arginine deiminase 4 in pluripotency: The emerging role of citrullinated histone H1 in cellular programming
Histone post-translational modifications (PTM) alter the chromatin architecture, generating ‘open’ and ‘closed’ states, and these structural changes can modulate gene expression under specific cellular conditions. While ...
Protein Arginine Deiminase 2 Binds Calcium in an Ordered Fashion: Implications for Inhibitor Design
(Amer Chemical Soc, 2015-04-01)
Protein arginine deiminases (PADs) are calcium-dependent histone-modifying enzymes whose activity is dysregulated in inflammatory diseases and cancer. PAD2 functions as an Estrogen Receptor (ER) coactivator in breast cancer ...
Chemical Proteomic Platform To Identify Citrullinated Proteins
Anti-citrullinated protein antibodies (ACPAs) are a hallmark of rheumatoid arthritis (RA) and are routinely used for disease diagnosis. Protein citrullination is also increased in cancer and other autoimmune disorders, ...
Crystal structure of the MACPF domain of human complement protein C8 alpha in complex with the C8 gamma subunit
(Academic Press Ltd Elsevier Science Ltd, 2008-05-29)
Human C8 is one of five complement components (C5b, C6, C7, C8 and C9) that assemble on bacterial membranes to form a pore-like structure referred to as the "membrane attack complex" (MAC). C8 contains three genetically ...
Chemical and Biological Methods to Detect Post-Translational Modifications of Arginine
Posttranslational modifications (PTMs) of protein embedded arginines are increasingly being recognized as playing an important role in both prokaryotic and eukaryotic biology, and it is now clear that these PTMs modulate ...
