1. Enter a WormBase ID, a gene symbol (e.g. hbl-1), or a Refseq ID (e.g. NM_076575):

2. Select one of the following:

a conserved* microRNA family

a nonconserved* microRNA family

*conserved = conserved across C. elegans and C. briggsae

TargetScan predicts biological targets of miRNAs by searching for the presence of conserved 8mer and 7mer sites that match the seed region of each miRNA (ref. 1). As an option, nonconserved sites are also predicted.

TargetScanWorm displays predicted regulatory targets of worm microRNAs (ref. 2).

This website considers matches to sites in the 3-species 3' UTRs.
