Mitochondrial-Encoded Peptide MOTS-c, Diabetes, and Aging-Related Diseases [PDF]

Diabetes & Metabolism Journal, 2023
Mitochondria are complex metabolic organelles with manifold pathophysiological implications in diabetes. Currently published mitochondrial-encoded peptides, which are expressed from the mitochondrial open reading frame of the 12S ribosomal RNA type-c ...

Signal Peptide Cleavage and Internal Targeting Signals Direct the Hepatitis C Virus p7 Protein to Distinct Intracellular Membranes [PDF]

Journal of Virology, 2005
ABSTRACT The hepatitis C virus (HCV) p7 protein forms an amantadine-sensitive ion channel required for viral replication in chimpanzees, though its precise role in the life cycle of HCV is unknown. In an attempt to gain some insights into p7 function, we examined the intracellular localization of p7 using epitope tags and an anti-p7 peptide ...

A Cyclic Peptide Mimicking the Third Intracellular Loop of the V2 Vasopressin Receptor Inhibits Signaling through Its Interaction with Receptor Dimer and G Protein [PDF]

Journal of Biological Chemistry, 2004
In this study, we investigated the mechanism by which a peptide mimicking the third cytoplasmic loop of the vasopressin V2 receptor inhibits signaling. This loop was synthesized as a cyclic peptide (i3 cyc) that adopted defined secondary structure in solution.

Analysis of the Yeast Peptidome and Comparison with the Human Peptidome. [PDF]

PLoS ONE, 2016
Peptides function as signaling molecules in species as diverse as humans and yeast. Mass spectrometry-based peptidomics techniques provide a relatively unbiased method to assess the peptidome of biological samples.

Regulator of G-Protein Signaling (RGS) Protein Modulation of Opioid Receptor Signaling as a Potential Target for Pain Management

Frontiers in Molecular Neuroscience, 2020
Opioid drugs are the gold standard for the management of pain, but their use is severely limited by dangerous and unpleasant side effects. All clinically available opioid analgesics bind to and activate the mu-opioid receptor (MOR), a heterotrimeric G ...

Signal Protein-Derived Peptides as Functional Probes and Regulators of Intracellular Signaling [PDF]

Journal of Amino Acids, 2011
The functionally important regions of signal proteins participating in their specific interaction and responsible for transduction of hormonal signal into cell are rather short in length, having, as a rule, 8 to 20 amino acid residues. Synthetic peptides corresponding to these regions are able to mimic the activated form of full-size signal protein and
