Phosphorylation disrupts long-distance electron transport in cytochrome c
(Springer Nature, 2022)
t has been recently shown that electron transfer between mitochondrial cytochrome c and the cytochrome c1 subunit of the cytochrome bc1 can proceed at long-distance through the aqueous solution. Cytochrome c is thought to ...

The Histone Chaperones SET/TAF-1β and NPM1 Exhibit Conserved Functionality in Nucleosome Remodeling and Histone Eviction in a Cytochrome c-Dependent Manner
(Wiley-Blackwell, 2023)
Chromatin homeostasis mediates essential processes in eukaryotes, where histone chaperones have emerged as major regulatory factors during DNA replication, repair, and transcription. The dynamic nature of these processes, ...

Molecular basis of FIR-mediated c-myc transcriptional control
(Nature Research, 2010)
The far upstream element (FUSE) regulatory system promotes a peak in the concentration of c-Myc during cell cycle. First, the FBP transcriptional activator binds to the FUSE DNA element upstream of the c-myc promoter. Then, ...

A structural insight into the C-terminal RNA recognition motifs of T-cell intracellular antigen-1 protein
(Elsevier, 2011)
T-cell intracellular antigen-1 (TIA-1) plays a pleiotropic role in cell homeostasis through the regulation of alternative pre-mRNA splicing and mRNA translation by recognising uridine-rich sequences of RNAs. TIA-1 contains ...

The Dynamics of the Human Leukocyte Antigen Head Domain Modulates Its Recognition by the T-Cell Receptor
(Public Library of Science, 2016)
Generating the immune response requires the discrimination of peptides presented by the human leukocyte antigen complex (HLA) through the T-cell receptor (TCR). However, how a single amino acid substitution in the antigen ...

Post-translational Control of RNA-Binding Proteins and Disease-Related Dysregulation
(Frontiers Media S.A., 2021)
Cell signaling mechanisms modulate gene expression in response to internal and external stimuli. Cellular adaptation requires a precise and coordinated regulation of the transcription and translation processes. The ...

Modulation of copper site properties by remote residues determines the stability of plastocyanins
(Elsevier, 2010)
The metal cofactor determines the thermal stability in cupredoxins, but how the redox state of copper modulates their melting points remains unknown. The metal coordination environment is highly conserved in cyanobacterial ...

An evolutionary analysis of the reaction mechanisms of photosystem I reduction by cytochrome c6 and plastocyanin
(Elsevier, 2002)
Photosystem I reduction by the soluble metalloproteins cytochrome c6 and plastocyanin, which are alternatively synthesized by some photosynthetic organisms depending on the relative availability of copper and iron, has ...

Protein crosslinking improves the thermal resistance of plastocyanin immobilized on a modified gold electrode
(Elsevier, 2018-12)
Increasing the thermal stability of immobilized proteins is a motivating goal for improving the performance of electrochemical biodevices. In this work, we propose the immobilization of crosslinked plastocyanin from the ...

Proposed mechanism for regulation of H2O2-induced programmed cell death in plants by binding of cytochrome c to 14-3-3 proteins
(Wiley-Blackwell, 2021-04)
Programmed cell death (PCD) is crucial for development and homeostasis of all multicellular organisms. In human cells, the double role of extra-mitochondrial cytochrome c in triggering apoptosis and inhibiting survival ...
