Mechanisms of sphingolipid functions during heat stress in "Saccharomyces cerevisiae" [PDF]
Sphingolipids are important membrane constituents in all eukaryotic cells. Ongoing sphingolipid synthesis is required for a variety of cellular processes including response to heat shock.

Processing of sphingolipid activator proteins and the topology of lysosomal digestion.
Plasma membrane derived glycosphingolipids (GSLs) destined for digestion are internalized through the endocytic pathway and delivered to the lysosomes. There, GSLs are degraded by the action of exohydrolases, which are supported, in the case of GSLs with

Gelsolin induces colorectal tumor cell invasion via modulation of the urokinase-type plasminogen activator cascade [PDF]
Gelsolin is a cytoskeletal protein which participates in actin filament dynamics and promotes cell motility and plasticity. Although initially regarded as a tumor suppressor, gelsolin expression in certain tumors correlates with poor prognosis and ...

The cationic region of Rhes mediates its interactions with specific Gβ subunits [PDF]
Ras homologue enriched in striatum (Rhes) is a small monomeric G protein which functions in a variety of cellular processes, including attenuation of G protein-coupled receptor (GPCR)signalling.

Urokinase-Type Plasminogen Activator Promotes Paracellular Transmigration of Neutrophils Via Mac-1, But Independently of Urokinase-Type Plasminogen Activator Receptor [PDF]
Background: Urokinase-type plasminogen activator (uPA) has recently been implicated in the pathogenesis of ischemia-reperfusion (I/R) injury. The underlying mechanisms remain largely unclear.

CPTP: A sphingolipid transfer protein that regulates autophagy and inflammasome activation [PDF]
The macroautophagy/autophagy and inflammasome pathways are linked through their roles in innate immunity and chronic inflammatory disease. Ceramide-1-phosphate (C1P) is a bioactive sphingolipid that regulates pro-inflammatory eicosanoid production. Whether C1P also regulates autophagy and inflammasome assembly/activation is not known. Here we show that

Saposins A, B, C, and D, which are required for the enzymatic hydrolysis of sphingolipids by specific lysosomal hydrolases, are produced by proteolytic processing of their common precursor protein, prosaposin.

Identification of novel sphingolipid-binding motifs in mammalian membrane proteins [PDF]
Specific interactions between transmembrane proteins and sphingolipids is a poorly understood phenomenon, and only a couple of instances have been identified.

Do Sphingolipids Control Viral Membrane Protein Activity? [PDF]
The membrane-behaviour of the matrix (M) protein from respiratory syncytical virus, a prototypical enveloped virus, has been characterised by surface techniques (tensiometry, Brewster angle microscopy and atomic force microscopy) and experiments using lipid bilayers (FRET, light microscopy).

Novel bi- and trifunctional inhibitors of tumor-associated proteolytic systems [PDF]
Serine proteases, cysteine proteases, and matrix metalloproteinases (MMPs) are involved in cancer cell invasion and metastasis. Recently, a recombinant bifunctional inhibitor (chCysuPA(19-31)) directed against cysteine proteases and the urokinasetype ...
