- Phylogenetic profiling resolves early emergence of PRC2 and illuminates its functional core
This study strengthens the support for PRC2 emergence before the diversification of eukaryotes, detects a common presence of E(z) and ESC, indicating a conserved core, identifies diverse VEFS-Box Su(z)12 candidate proteins, and proposes a substrate specificity shift during E(z) evolution.
- SMN-deficient cells exhibit increased ribosomal DNA damage
SMN deficiency leads to elevated ribosomal DNA damage that results in impaired ribosomal RNA synthesis and translation and is accompanied by a motor neuron-specific down-regulation of DDX21 protein.
- Tricalbin proteins regulate plasma membrane phospholipid homeostasis
The extended synaptotagmin (E-Syt) family are conserved proteins that function at membrane contacts. This study reveals that yeast E-Syt family members regulate phospholipid homeostasis necessary for plasma membrane integrity.
- Polycomb group ring finger protein 6 suppresses Myc-induced lymphomagenesis
Max dimerizes with Mga to form the repressive complex PRC1.6; another PRC1.6 subunit, Pcgf6, suppresses Myc-induced lymphomagenesis but, unexpectedly, does so in a Mga- and PRC1.6-independent manner.
- A novel domain within the CIL regulates egress of IFITM3 from the Golgi and reveals a regulatory role of IFITM3 on the secretory pathway
In this work, it is revealed that the broad viral inhibitor IFITM3 is a previously unrecognized modulator of the functionalities of the cellular ER–Golgi secretory pathway.
- The hexosamine pathway and coat complex II promote malignant adaptation to nutrient scarcity
We present adaptive mechanisms of resistance of lung adenocarcinoma to their harsh microenvironment, which typically contains a lower glucose concentration compared with normal tissue.
- Functional and structural deficiencies of Gemin5 variants associated with neurological disorders
Gemin5 clinical variants perturbing the dimerization module and the noncanonical RNA-binding site impair oligomerization, RNA–protein interaction networks, ribosome association, and protein stability.
- Profiles of telomeric repeats in Insecta reveal diverse forms of telomeric motifs in Hymenopterans
A bioinformatic pipeline for telomeric repeat motif detection was applied to 129 insect species and identified diverse forms of telomeric motifs in Hymenopterans, including canonical 5-bp, novel 8- and 9-bp forms, suggesting extraordinary evolutionary fluidity of telomeric repeat in Hymenopterans.
- Quantitative analysis of nuclear pore complex organization in Schizosaccharomyces pombe
Characterization of nuclear pores in Schizosaccharomyces pombe identifies regions of heterogeneous NPC density and composition and shows that NPCs are excluded near the spindle pole body by Lem2-mediated centromere tethering.
- ESCRT-I fuels lysosomal degradation to restrict TFEB/TFE3 signaling via the Rag-mTORC1 pathway
ESCRT-I deficiency impairs lysosome membrane turnover and induces homeostatic responses to lysosomal nutrient starvation including activation of MiT-TFE signaling caused by inhibition of the substrate-specific mTORC1 pathway.
