Structural comparison of unconventional G protein YchF with heterotrimeric G protein and small G protein

open access: yesPlant Signaling & Behavior, 2022
Guanine nucleotide-binding (G) proteins, namely, phosphate-binding (P) loop GTPases, play a critical role in life processes among different species. Based on the structural characteristics, G proteins can be divided into heterotrimeric G proteins, small ...

Is the intrinsic disorder of proteins the cause of the scale-free architecture of protein-protein interaction networks? [PDF]

open access: yesarXiv, 2006
In protein-protein interaction networks certain topological properties appear to be recurrent: networks maps are considered scale-free. It is possible that this topology is reflected in the protein structure. In this paper we investigate the role of protein disorder in the network topology.

Refining the Protein-Protein Interactome using Gene Expression Data [PDF]

open access: yesarXiv, 2010
Proteins interact with other proteins within biological pathways, forming connected subgraphs in the protein-protein interactome (PPI). Proteins are often involved in multiple biological pathways which complicates interpretation of interactions between proteins.

Comparative structural dynamic analysis of GTPases.

open access: yesPLoS Computational Biology, 2018
GTPases regulate a multitude of essential cellular processes ranging from movement and division to differentiation and neuronal activity. These ubiquitous enzymes operate by hydrolyzing GTP to GDP with associated conformational changes that modulate ...

Structural basis of human PDZD8–Rab7 interaction for the ER-late endosome tethering

open access: yesScientific Reports, 2021
The membrane contact sites (MCSs) between the ER and late endosomes (LEs) are essential for the regulation of endosomal protein sorting, dynamics, and motility.

Protein token: a dynamic unit in protein interactions [PDF]

open access: yesarXiv, 2018
In this study, we introduced a new unit, named "protein token", as a dynamic protein structural unit for protein-protein interactions. Unlike the conventional structural units, protein token is not based on the sequential or spatial arrangement of residues, but comprises remote residues involved in cooperative conformational changes during protein ...

Nucleotide based covalent inhibitors of KRas can only be efficient in vivo if they bind reversibly with GTP-like affinity

open access: yesScientific Reports, 2017
Simple reversible competitive inhibition of nucleotide binding of GTP to Ras family GTPases has long been recognized as an unlikely approach to manipulating the activity of such proteins for experimental or therapeutic purposes.

Global protein function prediction in protein-protein interaction networks [PDF]

open access: yesNature Biotech. 21, 697-700 (2003), 2003
The determination of protein functions is one of the most challenging problems of the post-genomic era. The sequencing of entire genomes and the possibility to access gene's co-expression patterns has moved the attention from the study of single proteins or small complexes to that of the entire proteome. In this context, the search for reliable methods
