Identification of subcellular compartments involved in biosynthetic processing of cathepsin D.
We have assigned the biosynthetic processing steps of cathepsin D to intracellular compartments which are involved in its transport to lysosomes in HepG2 cells. Cathepsin D was synthesized as a 51-kDa proenzyme. After formation of 51-55-kDa intermediates due to processing of N-linked oligosaccharides, procathepsin D was proteolytically processed to an ...

Uptake and subcellular processing of 59Fe-125I-labelled transferrin by rat liver [PDF]
The uptake of transferrin and iron by the rat liver was studied after intravenous injection or perfusion in vitro with diferric rat transferrin labelled with 125I and 59Fe. It was shown by subcellular fractionation on sucrose density gradients that 125I-transferrin was predominantly associated with a low-density membrane fraction, of similar density to

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Mapping subcellular RNA localization with proximity labeling
The subcellular localization of RNA is critical to a variety of physiological and pathological processes. Dissecting the spatiotemporal regulation of the transcriptome is key to understanding cell function and fate.

tRNA Processing and Subcellular Trafficking Proteins Multitask in Pathways for Other RNAs [PDF]
This article focuses upon gene products that are involved in tRNA biology, with particular emphasis upon post-transcriptional RNA processing and nuclear-cytoplasmic subcellular trafficking. Rather than analyzing these proteins solely from a tRNA perspective, we explore the many overlapping functions of the processing enzymes and proteins involved in ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Steroid hormones and subcellular processes [PDF]
Aldosterone administered intraperitoneally induced an increase in the rate of renal RNA synthesis in the rat. A maximum response of 130 percent of control occurred 1.5 hours after injection.

DNA damage-induced translocation of S100A11 into the nucleus regulates cell proliferation
Background Proteins are able to react in response to distinct stress stimuli by alteration of their subcellular distribution. The stress-responsive protein S100A11 belongs to the family of multifunctional S100 proteins which have been implicated in ...

Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
