The transport of proteins between the nucleus and the cytosol is a vital process regulating cellular activity. The ability to spatiotemporally control the nucleocytoplasmic transport of a protein of interest allows for elucidating its function taking into account the dynamic and heterogeneous nature of biological processes contrary to conventional knockin, knockout, and chemically induced overexpression strategies. We recently developed two optogenetic tools, called LINuS and LEXY, for reversibly controlling with blue light the nuclear import and export of proteins of interest, respectively. Here we describe how to use them to control the localization of a protein of interest in cultured mammalian cells using a fluorescence microscope.

This study aimed to investigate the effects of radiation (RT) on protein and protein S-palmitoylation levels in esophageal cancer (EC) cell lines. EC cells ( = 6) were randomly divided into RT and negative control. The results revealed that 592 proteins were identified in the RT group, including 326 upregulation proteins and 266 downregulation proteins.

Na⁺/H⁺ exchanger regulatory factor 2 (NHERF2) is a nucleocytoplasmic protein initially identified as a regulator of membrane-bound sodium-hydrogen exchanger 3 (NHE3). In the cytoplasm, NHERF2 regulates the activity of G protein-coupled receptors (GPCRs), including beta-2 adrenergic receptor (2β-AR), lysophosphatidic acid receptor 2, and parathyroid hormone type 1 receptor. In the nucleus, NHERF2 acts as a coregulator of transcription factors such as sex-determining region Y protein (SRY), involved in male sex determination, and estrogen receptor alpha (ERα).

Nucleocytoplasmic large DNA viruses (NCLDVs) are known to infect phytoplankton and play a significant role in regulating their population dynamics. In this study, we aimed to investigate the co-occurrence patterns between phytoplankton and NCLDVs in the southern coastal ecosystem of South Korea. We collected seawater every month from March 2018 to December 2020 and analyzed the samples using Cytochrome c Oxidase subunit I metabarcoding and metagenomic analyses.

Changing environmental conditions necessitate rapid adaptation of cytoplasmic and nuclear volumes. We use the slime mold Dictyostelium discoideum, known for its ability to tolerate extreme changes in osmolarity, to assess which role nuclear pore complexes (NPCs) play in achieving nuclear volume adaptation and relieving mechanical stress. We capitalize on the unique properties of D.

The medicinal beetle Blaps rynchopetera is recognized for its antibacterial, anti-inflammatory, and immune-regulating properties. This study utilized metaviromics technology to systematically characterize the viral community within the gut of B. rynchopetera through high-throughput sequencing of gut contents, with a specific focus on the composition of its bacteriophage community.
