ProteomicsPARG is Essential for Pol-theta-Mediated DNA End-Joining by Removing Repressive Poly-ADP Ribose Marks
DNA polymerase theta (Pol-theta)-mediated end-joining (TMEJ) repairs DNA double-strand breaks and confers resistance to genotoxic agents. How Pol-theta is regulated at the molecular level to exert TMEJ remains unknown. We find that Pol-theta interacts with and is PARylated by PARP1 in vitro and in c...

ProteomicsDual-acting IspH inhibitors kill Gram-negative bacteria and mobilize immune clearance
Isoprenoids are vital to all organisms in supporting core functions of life, like respiration and membrane stability. IspH, an enzyme in the methyl erythritol phosphate pathway of isoprenoid synthesis, is essential to gram-negative bacteria, mycobacteria and apicomplexans. The IspH substrate, HMBPP,...

ProteomicsWnt signaling inhibits Casein kinase 1a activity by modulating its interaction with Protein phosphatase 2A
The mechanism by which Wnt signaling, an essential pathway controlling development and disease, stabilizes beta-Catenin has been a subject of debate over the last three decades. Casein kinase 1alpha (CK1a) functions as a pivotal negative regulator of this signaling pathway, initiating the events tha...

ProteomicsStromal Changes in The Aged Lung Induce an Emergence From Melanoma Dormancy
Disseminated cancer cells (DCCs) that escape the primary site can seed in distal tissues, but may take several years, or even decades to grow out into overt metastases, a phenomenon termed tumor dormancy. Despite its importance in metastasis and residual disease, few studies have been able to succes...
