The T2238C human atrial natriuretic peptide molecular variant and the risk of cardiovascular diseases [PDF]
Atrial natriuretic peptide (ANP) is a cardiac hormone which plays important functions to maintain cardio-renal homeostasis. The peptide structure is highly conserved among species. However, a few gene variants are known to fall within the human ANP gene.

Roles of Rap1 signaling in tumor cell migration and invasion
Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization.

A metazoan/plant-like capping enzyme and cap modified nucleotides in the unicellular eukaryote Trichomonas vaginalis. [PDF]
The cap structure of eukaryotic messenger RNAs is initially elaborated through three enzymatic reactions: hydrolysis of the 5'-triphosphate, transfer of guanosine through a 5'-5' triphosphate linkage and N7-methylation of the guanine cap.

Model for the unidirectional motion of a dynein molecule [PDF]
Cytoplasmic dyneins transport cellular organelles by moving on a microtubule filament. It has been found recently that depending on the applied force and the concentration of the adenosine triphosphate (ATP) molecules, dynein's step size varies. Based on these studies, we propose a simple model for dynein's unidirectional motion taking into account the

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

The Guanylate Cyclase C-cGMP Signaling Axis Opposes Intestinal Epithelial Injury and Neoplasia. [PDF]
Guanylate cyclase C (GUCY2C) is a transmembrane receptor expressed on the luminal aspect of the intestinal epithelium. Its ligands include bacterial heat-stable enterotoxins responsible for traveler\u27s diarrhea, the endogenous peptide hormones ...

Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

CD13 regulation of membrane recycling: implications for cancer dissemination
Membrane recycling is critical to numerous cell functions and its dysregulation contributes to cancer and metastasis. We established that activation of the transmembrane molecule aminopeptidase N (ANPEP, also known as CD13) tethers the IQ motif ...

The synthesis of guanosine 5'-diphosphate D-glucose by enzyme extracts of mung beans (Phaseolus aureus) and other higher plants [PDF]
In response to a statement in the recent literature that the enzyme responsible for the synthesis of guanosine 5'-diphosphate D-glucose had been found only in pea seeds, enzyme extracts were prepared from a variety of higher plants.
