The subcellular localization of RNAs is regulated by cis-regulatory elements together with interacting trans factors. Here we describe a high-throughput sequencing-based method named REL-seq (RNA elements for subcellular localization by sequencing) to identify the cis-elements that contribute to RNA subcellular localization. By coupling REL-seq with random mutagenesis (mutREL-seq), we can further narrow down the cis-elements to key motifs at single-nucleotide resolution.
