AlphaFold-Multimer provided novel insights into the functional roles of previously uncharacterized proteins in complexes. Our web portal ( www.yeast-interactome.org ) enables extensive exploration Ito, T. et al.

CenKR is an essential two-component system and directly controls transcription of RSP_1200, a previously uncharacterized gene that, when disrupted, led to the production of extracellular lipid vesicles and a higher sensitivity to chemicals that act at the cell envelope (30). Here, using yeast two-hybrid screening, followed by immunoprecipitation and pull-down assays, we identify a previously uncharacterized protein, FAM47E, as an interaction partner of PRMT5. We report that FAM47E regulates steady-state levels of PRMT5 by affecting its stability through inhibition of its proteasomal degradation. The elongation period of cotton fiber development is crucial for ensuring cotton quality. However, the molecular mechanisms underlying fiber elongation remain unclear. This study reveals that SER02 _ A11, which is preferentially expressed during the fiber elongation period, encodes serine protease inhibitors (serpins). A previously uncharacterized SNP 517th

In order to achieve that, we constructed a yeast two-hybrid mini-library harboring the majority of the previously identified lumenal proteins and lumenal domains of various thylakoid membrane proteins.

Bensig EO, Valadez-Cano C, Kuang Z, Freire IR, Reyes-Prieto A and MacLellan SR (2022) The two-component regulatory system CenK–CenR regulates expression of a previously uncharacterized protein required for salinity and oxidative CenKR is an essential two-component system and directly controls transcription of RSP_1200, a previously uncharacterized gene that, when disrupted, led to the production of extracellular lipid vesicles and a higher sensitivity to chemicals that act at the cell envelope (30). Tethering factors mediate initial interaction of transport vesicles with target membranes. Soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptors (SNAREs) enable consequent docking and membrane fusion. We demonstrate that the vesicle tether conserved oligomeric Golgi (COG) co

MacLellan 2 * We developed a semi-quantitative statistical approach to score protein interactions and defined a high quality map. The map recovers many known, and hundreds of previously uncharacterized protein complexes, thus providing functional associations and biological context for 586 proteins that previously lacked annotation.

The virulence properties of Vibrio proteolyticus are investigated and a previously unstudied member of the leukocidin family of pore-forming toxins is identified as the virulence factor responsible for the observed cytotoxicity in eukaryotic cells, as well as a plethora of additional putative virulence factors secreted by this bacterium.

Using a Bacterial Adenylate Cyclase Two-Hybrid (BACTH) system33, in vivo protein protein interactions were found between (i) NifS and NifU; (ii) NifS and Nfu; (iii); NifU and Nfu; (iv) each of the RoseTTAFold2-Lite uses residue–residue coevolution and protein structure prediction to identify and structurally characterize protein–protein interactions in bacterial pathogens.

Use of the yeast two-hybrid system has provided definition to many previously uncharacterized pathways through the identification and characterization of novel protein-protein interactions. The two-hybrid system uses the bi-functional nature of transcription factors, such as the yeast enhancer Gal4, Various virulence determinants have been identified and studied in vibrios. These include protein secretion systems and the toxins that they deliver. Some vibrios (e.g., Vibrio vulnificus and Vibrio cholerae) mostly rely on toxins secreted into the environment by the type I and type II secretion systems to mediate virulence

The potential physical interaction between RnpM and RnpA was first tested using a bacterial two-hybrid system that is based on the reconstitution of adenylate cyclase and the resulting expression of the lac operon in E. coli upon interaction of the two partner proteins.

The N-terminal helical domain is closely packed together with the putative C-terminal cyclophilin domain and establishes a strong intramolecular interaction, thereby preventing the access of the cyclophilin domain to other proteins. This was further verified by protein-protein interaction assays using the yeast two-hybrid system.

Protein-protein interaction networks (PPINs) have been created for several organisms, including humans, primarily as results of high-throughput screenings, such as yeast two-hybrid (Y2H). Their unequivocal use to understand events underlying human pathophysiology is promising in identifying genes and proteins associated with diseases.

Functional proteomics could be instrumental in reducing the annotation gap by systematically associating uncharacterized proteins with proteins of known function and thereby assigning them to The network had 22 925 protein interaction pairs which involved 2 214 proteins. A total of 160 previously uncharacterized proteins were annotated in this network.

This approach correctly predicts a functional category for 72% of the 1,393 characterized proteins with at least one partner of known function, and has been applied to predict functions for 364 previously uncharacterized proteins. The N-terminal helical domain is closely packed together with the putative C-terminal cyclophilin domain and establishes a strong intramolecular interaction, thereby preventing the access of the cyclophilin domain to other proteins. This was further verified by protein-protein interaction assays using the yeast two-hybrid system.
