The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
FEBS Letters, EarlyView.Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Cell Communication and SignalingAutophagy is crucial for appressorium development and host invasion by phytopathogenic fungi, including Magnaporthe oryzae. During appressorium maturation, many organelles, such as nuclei, in the conidia need to be degraded through autophagy to be ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Nuclear Pore-Targeting Complex and Its Role on Nuclear Protein Transport.
Archives of Histology and Cytology, 1996 The process of selective nuclear protein transport is divided into at least two steps: 1) ATP-independent, nuclear localization signal (NLS)-dependent binding to the cytoplasmic face of nuclear pores and 2) ATP-dependent translocation through the nuclear pores.

In Situ Analysis of Spatial Relationships between Proteins of the Nuclear Pore Complex [PDF]
Biophysical Journal, 2002 Macromolecular transport between the nucleus and cytoplasm occurs through the nuclear pore complexes (NPCs). The NPC in the budding yeast Saccharomyces cerevisiae is a 60-MDa structure embedded in the nuclear envelope and composed of ~30 proteins, termed nucleoporins or nups.

Murine leukemia virus infection of non-dividing dendritic cells is dependent on nucleoporins.
PLoS PathogensRetroviral reverse transcription starts within the capsid and uncoating and reverse transcription are mutually dependent. There is still debate regarding the timing and cellular location of HIV's uncoating and reverse transcription and whether it occurs ...

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
