BiomeNet: a database for construction and analysis of functional interaction networks for any species with a sequenced genome

Abstract

Motivation Owing to advanced DNA sequencing and genome assembly technology, the number of species with sequenced genomes is rapidly increasing. The aim of the recently launched Earth BioGenome Project is to sequence genomes of all eukaryotic species on Earth over the next 10 years, making it feasible to obtain genomic blueprints of the majority of animal and plant species by this time. Genetic models of the sequenced species will later be subject to functional annotation, and a comprehensive molecular network should facilitate functional analysis of individual genes and pathways. However, network databases are lagging behind genome sequencing projects as even the largest network database provides gene networks for less than 10% of sequenced eukaryotic genomes, and the knowledge gap between genomes and interactomes continues to widen. Results We present BiomeNet, a database of 95 scored networks comprising over 8 million co-functional links, which can build and analyze gene networks for any species with the sequenced genome. BiomeNet transfers functional interactions between orthologous proteins from source networks to the target species within minutes and automatically constructs gene networks with the quality comparable to that of existing networks. BiomeNet enables assembly of the first-in-species gene networks not available through other databases, which are highly predictive of diverse biological processes and can also provide network analysis by extracting subnetworks for individual biological processes and network-based gene prioritizations. These data indicate that BiomeNet could enhance the benefits of decoding the genomes of various species, thus improving our understanding of the Earth’ biodiversity.

[Retracted] Construction and Application of Music Audio Database Based on Collaborative Filtering Algorithm

“…By analyzing and adjusting the logical path of different database systems, Kim et al made the database reach a state of deep query in the construction process. Experiments show that the database established by this method can well improve the error correction and correction ability of the database in the retrieval process [12].…”

HumanNet v3: an improved database of human gene networks for disease research

“…Interologs ( 26 ), protein-protein interactions transferred from other species via orthology, can also map functional associations between genes of a target species. Many integrated gene networks include interologs because they often improve network coverage and prediction performance, especially when there are difficulties in obtaining sufficient edge information directly from the target species genes ( 27 ). Nonetheless, given that many small- and large-scale protein-protein interaction mapping projects for human genes were carried out in the past several years, interologs from other species may no longer supplement human interactome information.…”

Computational Network Inference for Bacterial Interactomics

“…1A ). Conservation has also been observed in regulatory ( 49 , 53 ), functional ( 54 ), and co-expression networks ( 55 – 59 ), allowing transfer of interactions in the same way. Since protein domains are vital to function, the presence of pairs of domains can be predictive of PPI ( Fig.…”
