  text: Transcription by RNA polymerase II (Pol II) can be repressed by noncoding
    RNA, including the human RNA Alu. However, the mechanism by which endogenous RNAs
    repress transcription remains unclear. Here we present cryogenic-electron microscopy
    structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA
    and RNA bind to Pol II during transcription elongation. Further, we show how distinct
    domains of the general transcription factor TFIIF control repressive activity.
    Together, we reveal how a noncoding RNA can regulate mammalian gene expression.

  text: Transcription-coupled nucleotide excision repair (TC-NER) efficiently eliminates
    DNA damage that impedes gene transcription by RNA polymerase II (RNA Pol II).
    TC-NER is initiated by the recognition of lesion-stalled RNA Pol II by CSB, which
    recruits the CRL4CSA ubiquitin ligase and UVSSA. RNA Pol II ubiquitylation at
    RPB1-K1268 by CRL4CSA serves as a critical TC-NER checkpoint, governing RNA Pol
    II stability and initiating DNA damage excision by TFIIH recruitment. However,
    the precise regulatory mechanisms of CRL4CSA activity and TFIIH recruitment remain
    elusive. Here, we reveal human serine/threonine-protein kinase 19 (STK19) as a
    TC-NER factor, which is essential for correct DNA damage removal and subsequent
    transcription restart. Cryogenic electron microscopy (cryo-EM) studies demonstrate
    that STK19 is an integral part of the RNA Pol II-TC-NER complex, bridging CSA,
    UVSSA, RNA Pol II, and downstream DNA. STK19 stimulates TC-NER complex stability
    and CRL4CSA activity, resulting in efficient RNA Pol II ubiquitylation and correct
    UVSSA and TFIIH binding. These findings underscore the crucial role of STK19 as
    a core TC-NER component.

  text: Vaccinia-related kinase 1 (VRK1) and the δ and ε isoforms of casein kinase
    1 (CK1) are linked to various disease-relevant pathways. However, the lack of
    tool compounds for these kinases has significantly hampered our understanding
    of their cellular functions and therapeutic potential. Here, we describe the structure-based
    development of potent inhibitors of VRK1, a kinase highly expressed in various
    tumor types and crucial for cell proliferation and genome integrity. Kinome-wide
    profiling revealed that our compounds also inhibit CK1δ and CK1ε. We demonstrate
    that dihydropteridinones 35 and 36 mimic the cellular outcomes of VRK1 depletion.
    Complementary studies with existing CK1δ and CK1ε inhibitors suggest that these
    kinases may play overlapping roles in cell proliferation and genome instability.
    Together, our findings highlight the potential of VRK1 inhibition in treating
    p53-deficient tumors and possibly enhancing the efficacy of existing cancer therapies
    that target DNA stability or cell division.

  text: Transcription by RNA polymerase II (Pol II) can be repressed by noncoding
    RNA, including the human RNA Alu. However, the mechanism by which endogenous RNAs
    repress transcription remains unclear. Here we present cryo-electron microscopy
    structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA
    and RNA bind to Pol II during transcription elongation. Further, we show how domains
    of the general transcription factor TFIIF affect complex dynamics and control
    repressive activity. Together, we reveal how a non-coding RNA can regulate mammalian
    gene expression.

abstract:

  text: The actin cytoskeleton, a dynamic network of actin filaments and associated
    F-actin–binding proteins, is fundamentally important in eukaryotes. α-Actinins
    are major F-actin bundlers that are inhibited by Ca2+ in nonmuscle cells. Here
    we report the mechanism of Ca2+-mediated regulation of Entamoeba histolytica α-actinin-2
    (EhActn2) with features expected for the common ancestor of Entamoeba and higher
    eukaryotic α-actinins. Crystal structures of Ca2+-free and Ca2+-bound EhActn2
    reveal a calmodulin-like domain (CaMD) uniquely inserted within the rod domain.
    Integrative studies reveal an exceptionally high affinity of the EhActn2 CaMD
    for Ca2+, binding of which can only be regulated in the presence of physiological
    concentrations of Mg2+. Ca2+ binding triggers an increase in protein multidomain
    rigidity, reducing conformational flexibility of F-actin–binding domains via interdomain
    cross-talk and consequently inhibiting F-actin bundling. In vivo studies uncover
    that EhActn2 plays an important role in phagocytic cup formation and might constitute
    a new drug target for amoebic dysentery.
