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

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

Synaptic GAP and GEF Complexes Cluster Proteins Essential for GTP Signaling
Scientific Reports, 2017 GTPase-activating proteins (GAPs) and guanine exchange factors (GEFs) play essential roles in regulating the activity of small GTPases. Several GAPs and GEFs have been shown to be present at the postsynaptic density (PSD) within excitatory glutamatergic ...

Deconstruction of the Ras switching cycle through saturation mutagenesis
eLife, 2017 Ras proteins are highly conserved signaling molecules that exhibit regulated, nucleotide-dependent switching between active and inactive states. The high conservation of Ras requires mechanistic explanation, especially given the general mutational ...

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

Lrg1 Regulates β (1,3)-Glucan Masking in
mBio, 2019 Candida albicans is among the most prevalent opportunistic human fungal pathogens. The ability to mask the immunogenic polysaccharide β (1,3)-glucan from immune detection via a layer of mannosylated proteins is a key virulence factor of C. albicans.

Develop machine learning based predictive models for engineering protein solubility [PDF]
arXiv, 2018 Protein activity is a significant characteristic for recombinant proteins which can be used as biocatalysts. High activity of proteins reduces the cost of biocatalysts. A model that can predict protein activity from amino acid sequence is highly desired, as it aids experimental improvement of proteins.
