Open AccessDynamic movement of the Golgi unit and its glycosylation enzyme zones
Knowledge on the distribution and dynamics of glycosylation enzymes in the Golgi is essential for better understanding this modification. Here, using a combination of CRISPR/Cas9 knockin technology and super-r...

Open AccessCargo sorting zones in the trans-Golgi network visualized by super-resolution confocal live imaging microscopy in plants
The trans-Golgi network (TGN) has been known as a key platform to sort and transport proteins to their final destinations in post-Golgi membrane trafficking. However, how the TGN sorts proteins with different des...

Open AccessRole of Atg8 in the regulation of vacuolar membrane invagination
Cellular heat stress can cause damage, and significant changes, to a variety of cellular structures. When exposed to chronically high temperatures, yeast cells invaginate vacuolar membranes. In this study, we ...

Open AccessCOPII proteins exhibit distinct subdomains within each ER exit site for executing their functions
Secretory proteins are exported from special domains of the endoplasmic reticulum (ER) termed ER exit sites, via COPII-coated carriers. We recently showed that TANGO1 and Sec16 cooperatively organize mammalian...

Open AccessMiR-199a Inhibits Secondary Envelopment of Herpes Simplex Virus-1 Through the Downregulation of Cdc42-specific GTPase Activating Protein Localized in Golgi Apparatus
Because several studies have shown that exogenous miR-199a has antiviral effects against various viruses, including herpesviruses, we examined how miR-199a exerts its antiviral effects using epithelial tumour ...

Open AccessLive-cell visualization of excitation energy dynamics in chloroplast thylakoid structures
The intricate molecular processes underlying photosynthesis have long been studied using various analytic approaches. However, the three-dimensional (3D) dynamics of such photosynthetic processes remain unexpl...

Open AccessContact of cis-Golgi with ER exit sites executes cargo capture and delivery from the ER
Protein transport from the endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat complex II (COPII) vesicles. It has been believed that COPII vesicles containing cargo are released from the ER ...

Broadly tunable UV-blue picosecond pulsed laser and its application for biological imaging
We have achieved a rapid and random wavelength tuned picosecond pulsed laser and a widely tunable UV-blue picosecond pulsed laser by using the intracavity second harmonic generation of the laser. The tuning ra...

Structural basis for the Rho- and phosphoinositide-dependent localization of the exocyst subunit Sec3
The Sec3 subunit of the yeast exocyst complex tethers secretory vesicles to the plasma membrane for exocytosis through interactions with a small GTPase and PtdIns(4,5)P2 in the target membrane. A new study des...

Spatio-temporal images of growth-factor-induced activation of Ras and Rap1
G proteins of the Ras family function as molecular switches in many signalling cascades1,2,3; however, little is known about where they become activated in living cells. Here we use FRET (fluorescent resonance en...

p19ARF prevents G1 cyclin-dependent kinase activation by interacting with MDM2 and activating p53 in mouse fibroblasts
p19ARF encoded by the INK4a tumor suppressor gene locus functions upstream of p53 to induce cell cycle arrest. p19ARF can interact with MDM2 and p53 in cells ectopically overexpressing these three components, but...

Intravesical treatment of bladder cancer with recombinant human interferon-β
In order to examine its clinical efficacy, recombinant human interferon-β (rIFN-β) was instilled intravesically into 51 patients with superficial bladder cancer. Ten patients, who received intermittent intrave...
