    Yap1 safeguards mouse embryonic stem cells from excessive apoptosis during differentiation

    Lucy LeBlanc et al.
    During ES cell differentiation, Yap1 directly regulates apoptosis-related genes like Bcl-2 and Mcl-1 to attenuate apoptosis and promote cell survival to allow for successful cell fate changes.

    Amotl2a interacts with the Hippo effector Yap1 and the Wnt/β-catenin effector Lef1 to control tissue size in zebrafish

    Sobhika Agarwala et al.
    The cell junction-associated protein Amotl2a controls tissue size in the zebrafish lateral line primordium by limiting the activity of the Hippo effector Yap1 and the Wnt effector Lef1.

    Loss of functional BAP1 augments sensitivity to TRAIL in cancer cells

    Krishna Kalyan Kolluri et al.
    Loss of BAP1 function is associated with increased sensitivity to TRAIL and other death receptor agonists in malignant mesothelioma, where this is a frequent event, with immediate and actionable therapeutic implications.

    Fusion surface structure, function, and dynamics of gamete fusogen HAP2

    Juan Feng et al.
    Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.

    Signaling diversity enabled by Rap1-regulated plasma membrane ERK with distinct temporal dynamics

    Jeremiah Keyes et al.
    An individual extracellular signal regulates multiple cellular actions through differences in the temporal dynamics of spatially distinct populations of the central signaling enzyme, extracellular-signal regulated kinase.

    The multi-subunit GID/CTLH E3 ubiquitin ligase promotes cell proliferation and targets the transcription factor Hbp1 for degradation

    Fabienne Lampert et al.
    Proteomic, biochemical and cell-based analyses of the heterodecameric core GID/CTLH E3 ligase complex reveal its molecular architecture, activity determinants, and function in targeting the tumor suppressor Hbp1 and other substrates required for cell proliferation.

    The fail-safe mechanism of post-transcriptional silencing of unspliced HAC1 mRNA

    Rachael Di Santo et al.
    The unspliced HAC1 mRNA does not give rise to detectable protein in budding yeast, despite its cytoplasmic localization, due to a two-part post-transcriptional silencing mechanism.

    Release of human cytomegalovirus from latency by a KAP1/TRIM28 phosphorylation switch

    Benjamin Rauwel et al.
    Inactivation of KAP1 by mTOR-mediated phosphorylation releases human cytomegalovirus from latency, and has the potential to be used as a therapy to purge the virus from transplant organs.

    How lamina-associated polypeptide 1 (LAP1) activates Torsin

    Brian A Sosa et al.
    LAP1 adopts an AAA+ like fold that, while unable to bind nucleotide, can enhance ATPase activity in the neighboring TorsinA protomer in an unusual heterohexameric ring, via an arginine finger.

    Keratin 14-dependent disulfides regulate epidermal homeostasis and barrier function via 14-3-3σ and YAP1

    Yajuan Guo et al.
    Keratin filaments are revealed as novel regulators of entry into terminal differentiation in the epidermis via an ability to modulate YAP1 function and Hippo signaling.
