In order to enlarge coverage of the interaction maps, we also collected physical interactions for Caenorhabditis elegans (worm) and Saccharomyces cerevisiae (yeast).
Although there are some variations in the read coverage of the individual interactions, similar interactions can be observed by both 4C-seq and T2C.
In particular, efficient bioinformatics procedures enabling integrative analysis of multiple datasets from various screening approaches could increase the quality and coverage of the genetic interaction maps, with the aim of completing the genetic interaction networks in yeast and other organisms.
The coverage of the extracellular interaction network is not complete and MatrixDB is regularly updated.
As currently the coverage of the protein interaction network is limited, we suggest performing MATISSE analysis in addition to standard clustering analysis.
Thus, when evaluating a possible organization of the genetic interaction map there is a trade-off between the coverage of interactions and the number of modules and edges.
For these organisms in particular, consolidating PPIs from multiple databases affords much better coverage of the proteins whose interactions have been reported.
In general, such computational approach can facilitate the experimental efforts by improving the quality and coverage of the current genetic interaction networks, towards completing the still incomplete information of genetic interactions in yeast, which is - by and large - complementary to that obtained from the physical protein interactions and complexes [ 1, 5, 11, 17, 39, 40].
Thus, we used two measurements for optimality criteria: 1) The area under the precision versus recall curve for a random set of 2/3 and 1/3 of the membrane genes in GO Slim selected as training and test sets, respectively and 2) the increased coverage of membrane interactions reflected by the weight of network A in the logistic regression.
This may be due to evolutionary divergence or to differences between the current coverage of the two organisms' interaction maps.
