Bacterial resistance against antibiotic treatment has become a major threat to public health. Antimicrobial peptides (AMPs) have emerged as promising alternative agents for treatment of infectious diseases. This study characterizes novel synthetic peptides sequentially derived from the AMP centrocin...

Biliverdin reductase: more than a namesake - the reductase, its Peptide fragments, and biliverdin regulate activity of the three classes of protein kinase C.

Frontiers in pharmacology

Gibbs PE, Tudor C, Maines MD.
PMID: 22419908
Front Pharmacol. 2012 Mar 13;3:31. doi: 10.3389/fphar.2012.00031. eCollection 2012.

The expanse of human biliverdin reductase (hBVR) functions in the cells is arguably unmatched by any single protein. hBVR is a Ser/Thr/Tyr-kinase, a scaffold protein, a transcription factor, and an intracellular transporter of gene regulators. hBVR is an upstream...

Proteolytic degradation patterns of the receptor for advanced glycation end products peptide fragments correlate with their neuroprotective activity in Alzheimer's disease models.

Drug development research

Volpina OM, Koroev DO, Serebryakova MV, Volkova TD, Kamynina AV, Bobkova NV.
PMID: 34060112
Drug Dev Res. 2021 Dec;82(8):1217-1226. doi: 10.1002/ddr.21836. Epub 2021 May 31.

The receptor for advanced glycation end products (RAGE) plays an essential role in Alzheimer's disease (AD). We previously demonstrated that a fragment (60-76) of RAGE improved the memory of olfactory bulbectomized (OBX) and Tg 5 × FAD mice -...

Native CGRP Neuropeptide and Its Stable Analogue SAX, But Not CGRP Peptide Fragments, Inhibit Mucosal HIV-1 Transmission.

Frontiers in immunology

Mariotton J, Sams A, Cohen E, Sennepin A, Siracusano G, Sanvito F, Edvinsson L, Delongchamps NB, Zerbib M, Lopalco L, Bomsel M, Ganor Y.

BACKGROUND: The vasodilator neuropeptide calcitonin gene-related peptide (CGRP) plays both detrimental and protective roles in different pathologies. CGRP is also an essential component of the neuro-immune dialogue between nociceptors and mucosal immune cells. We previously discovered that CGRP is...

The kinetically controlled condensation reaction of Z-Gly-Trp-Met-OR(1) (R(1): Et, Al, Cam) and H-Asp-(OR(2))-Phe-NH(2) (R(2): H, Bu(t)) catalyzed by alpha-chymotrypsin deposited onto polyamide in organic media was studied. The effect of the drying process of the enzyme-support preparation, substrate concentrations,...

Responses of Cultured Astrocytes, C6 Glioma and 1321NI Astrocytoma Cells to Amyloid beta-Peptide Fragments.

The effect of amyloid beta-peptide (betaAP), which can have both neurotrophic or neurotoxic effects on neurons and has been implicated in the pathogenesis of Alzheimer's disease (AD), was studied on astrocytes using primary cultures and astrocyte cell lines (rat...

Phytochrome structure: Peptide fragments from the amino-terminal domain involved in protein-chromophore interactions.


Jones AM, Quail PH.
PMID: 24212743
Planta. 1989 May;178(2):147-56. doi: 10.1007/BF00393189.

We have undertaken a study of the structure of the amino-terminal domain of the phytochrome polypeptide purified from Avena sativa L. Amino-acid sequencing was used to indentify arginine 52 as the precise location of a conformation-specific cleavage of phytochrome...

Curr Opin Chem Biol. 2021 Oct;64:106-115. doi: 10.1016/j.cbpa.2021.05.004. Epub 2021 Jul 03.

The assembly of amyloidogenic peptides and proteins, such as the β-amyloid peptide, α-synuclein, huntingtin, tau, and islet amyloid polypeptide, into amyloid fibrils and oligomers is directly linked to amyloid diseases, such as Alzheimer's, Parkinson's, and Huntington's diseases, frontotemporal dementias,...
