About Yuval Tabach

Interests: small RNA-mediated pathways, MicroRNAs, RNAi, Phylogenetic profiling, bioinformatics, genomic data. Several recent studies have sought to identify novel genes in the small RNA-mediated pathways. Even as these gene lists are highly likely to contain novel candidates the limited overlap of these screens may indicate a large false positive rate and may reflect limited sensitivity and specificity. In an effort to more comprehensively identify genes that contribute to small RNA pathways, I experimentally and computationally collect different genome-scale data sets including: Phylogenetic profiles, protein-protein interaction, expression databases, RNAi phenotypes, genetic interactions, interolog interactions, mass spectrometry data and RNAi screens to detect genes involved in microRNA and siRNA. I am applying various bioinformatics and statistical methods to evaluate each dataset's predictive power and integrate the different resources and establishing a list of high-confidence candidate.
