PROTEIN FUNCTION PREDICTION 采用了Seq2Vec作为backbone,和PPI一样,只是用protbert和ontoprotein替换了嵌入层。 划分为三个子集(BPO,MFO,和CCO),并对模型在每个子集上的表现分别进行评估。 感觉ProtBert预训练的时候做的是MLM,OntoProtein做了MLM和在GO的图谱上训练过,所以做这个GO的预测应该是肯定会有提升的。 Pro...
根据数据类型,ppi预测方法分类为:genomic data, protein sequence, protein structure, PPI networks, gene expression, and annotations of gene function, localization, and process。基于genomic data数据分析conserved operon structure, fusion domains, phylogenetic profiles, and interologs。 很多研究基于蛋白质序列预...
Protein function predictionSpectral clusteringThe increasing availability of large-scale protein-protein interaction (PPI) data has made it possible to understand the basic components and organization of cell machinery from the network level. Many studies have shown that clustering protein interaction ...
to gain deeper insights into a target’s structure and function. When it comes to the investigation, IP, Co-IP and pull-down assays have become invaluable tools, which are built upon the affinity-based immobilization of a “bait” protein on a solid support, mostly magnetic or agarose beads...
decided to use a binding partner of unknown function. As part of a study of the regulation of mRNA decay in fission yeast, we performed RIP-chip experiments with the Exo2 protein, which is the S. pombe homologue of the XRN1 5′- > 3′ exonuclease [11] (Figure 2A). A TAP-tagged ...
Protein–protein interaction networks articles from across Nature Portfolio Atom RSS Feed Protein–protein interaction networks are the networks of protein complexes formed by biochemical events and/or electrostatic forces and that serve a distinct biological function as a complex.

For example, two proteins with low scores of the “protein binding” function term hardly interact with each other. We suggest that future work may consider leveraging function annotations to enhanc...
Predicting the structure of interacting protein chains is a fundamental step towards understanding protein function. Unfortunately, no computational method can produce accurate structures of protein complexes. AlphaFold2, has shown unprecedented levels of accuracy in modelling single chain protein structures. ...
Moreover, protein-protein interaction networks have been used to discover novel protein function (Fionda et al., 2009) and to identify functional modules and conserved interaction patterns (Fionda and Palopoli, 2011). Some studies on the structure of the protein-protein interaction networks of ...
