MicroRNAs regulate protein abundance on the post-transcriptional level. For experimental discovery they need to be co-expressed with their target mRNA and their effect needs to be measured on the protein level. These complications, led to a rise in interest in computational prediction of miRNAs. Computational miRNomics covers all areas ranging from pri- and pre-miRNA detection to the prediction of protein abundance and regulatory networks as well as their intersection with gene regulatory ones. The workshop aims to assemble experts in the field to establish a snapshot of the current state-of-the-art in computational miRNomics.
