Transition metal ions at the crossroads of mucosal immunity and microbial pathogenesis. [PDF]

, 2014
Transition metal ions are essential micronutrients for all living organisms. In mammals, these ions are often protein-bound and sequestered within cells, limiting their availability to microbes. Moreover, in response to infection, mammalian hosts further

Membrane cofactor protein of the complement system: alternative splicing of serine/threonine/proline-rich exons and cytoplasmic tails produces multiple isoforms that correlate with protein phenotype

Journal of Experimental Medicine, 1991
Membrane cofactor protein (MCP) is a complement regulatory protein that is expressed on human cells and cell lines as two relatively broad species with Mr of 58,000-68,000 and 48,000-56,000.

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Single‐Layer Radially Compartmentalized Paper Chip (RCP‐Chip) for Rapid Isothermal Multiplex Detection of SARS‐CoV‐2 Gene Targets

Advanced Sensor Research, EarlyView.
The single‐layer RCP‐Chip enables rapid, multiplexed detection of SARS‐CoV‐2 RNA using RT‐LAMP and gold nanoparticle‐enhanced colorimetric readouts. After sample loading, amplification occurs within radially arranged chambers, allowing simultaneous detection of E and N genes.

Structural and biophysical analysis of important biomedical enzymes and nano-architectures [PDF]

, 2008
Dopa decarboxylase (DDC) is an important enzyme in the catecholamine biosynthesis pathways. Catecholamines, e.g., dopamine, serotonin, etc. often are the major neuromodulators or neurotransmitters.

Mouse complement regulatory protein Crry/p65 uses the specific mechanisms of both human decay-accelerating factor and membrane cofactor protein

Journal of Experimental Medicine, 1995
Normal host cells are protected from the destructive action of complement by cell surface complement regulatory proteins. In humans, decay-accelerating factor (DAF) and membrane cofactor protein (MCP) play such a biologic role by inhibiting C3 and C5 ...

Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

Advanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

Structure of the extracellular portion of CD46 provides insights into its interactions with complement proteins and pathogens. [PDF]

PLoS Pathogens, 2010
The human membrane cofactor protein (MCP, CD46) is a central component of the innate immune system. CD46 protects autologous cells from complement attack by binding to complement proteins C3b and C4b and serving as a cofactor for their cleavage.

Transport Proteins Regulate the Flux of Metabolites and Cofactors Across the Membrane of Plant Peroxisomes

Frontiers in Plant Science, 2012
In land plants, peroxisomes play key roles in various metabolic pathways, including the most prominent examples, that is lipid mobilization and photorespiration. Given the large number of substrates that are exchanged across the peroxisomal membrane, a wide spectrum of metabolite and cofactor transporters is required and needs to be efficiently ...
