Identification of Chimeric RNAs Using RNA-Seq Reads and Protein-Protein Interactions of Translated Chimeras

Methods Mol Biol. 2020:2079:27-40. doi: 10.1007/978-1-4939-9904-0_3.

Abstract

Chimeric RNA moieties typically consist of exons from two genes expressed from different genomic locations and produced by chromosomal translocations, trans-splicing or transcription errors. Recent advances in next-generation sequencing procedures have opened new horizons for identification of novel chimeric transcripts in various diseases in a personalized manner. Here we describe the detailed computational procedures to identify chimeric transcripts using RNA-seq reads. Moreover, we elaborate on the domain-domain co-occurrence method to detect alterations in chimeric protein-protein interaction (ChiPPI) networks produced by chimeric RNA that are translated to chimeric proteins.

Keywords: Chimeric mRNA; Chimeric protein–protein interactions (ChiPPI); Domain–domain co-occurrence; Next-generation sequencing technology; RNA-seq reads.
