Ghosh D, Roy A, Ranjan A
FEBS Lett
. 2018 Aug;
592(16):2680-2692.
PMID: 30069866
Intracellular protein aggregation is characterized by accumulation of misfolded proteins. Chaperones, degradation machineries, and quality-control mechanisms counteract protein aggregation. In this study, we report that the ATPase valosin-containing protein (VCP/p97)...

Microbiology (Reading)
. 2018 Jul;
164(9):1133-1145.
PMID: 29993358
Lipid metabolism is critical to Mycobacterium tuberculosis survival and infection. Unlike Escherichia coli, which has a single FadR, the M. tuberculosis genome encodes five proteins of the FadR sub-family. While...

Aggregation-prone Regions in HYPK Help It to Form Sequestration Complex for Toxic Protein Aggregates
Ghosh D, Roy A, Ranjan A
J Mol Biol
. 2018 Feb;
430(7):963-986.
PMID: 29458128
Protein aggregates result from altered structural conformations and they can perturb cellular homeostasis. Prevention mechanisms, which function against protein aggregation by modulatory processes, are diverse and redundant. In this study,...

Biochemistry
. 2018 Jan;
57(13):2009-2023.
PMID: 29381348
Protein misfolding due to mutation(s) and/or generation of unstable intermediate state(s) can be the cause of aberrant aggregations, leading to cellular degeneration. While molecular signatures like amyloidogenic regions cause aggregation,...

. 2017 Jul;
3(7):e1700842.
PMID: 28740867
We report the fluorination of electrically insulating hexagonal boron nitride (h-BN) and the subsequent modification of its electronic band structure to a wide bandgap semiconductor via introduction of defect levels....

PMID: 27849052
Conventional adhesives show a decrease in the adhesion force with increasing temperature due to thermally induced viscoelastic thinning and/or structural decomposition. Here, we report the counter-intuitive behaviour of carbon nanotube...

Protein J
. 2016 Jun;
35(4):269-82.
PMID: 27325406
Regulators belonging to multiple antibiotic resistance regulator (MarR) family are widespread in prokaryotes and are involved in regulation of genes that are responsible for virulence and pathogenicity in most of...

Biochemistry
. 2016 Jan;
55(7):1120-34.
PMID: 26818787
Members of the Multiple antibiotic resistance Regulator (MarR) family of DNA binding proteins regulate transcription of a wide array of genes required for virulence and pathogenicity of bacteria. The present...

. 2015 Nov;
1(8):e1400198.
PMID: 26601246
One-dimensional (1D) carbon nanotubes (CNTs) and 2D single-atomic layer graphene have superior thermal, electrical, and mechanical properties. However, these nanomaterials exhibit poor out-of-plane properties due to the weak van der...

PMID: 23770584
Using a modified chemical vapor deposition (CVD) method, we have prepared a class of new graphene foams (GFs) doped with nitrogen, boron or both. Nitrogen-doped graphene foams (N-GFs) with a...
