Sequences gathered for seed by HMM_iterative_training Putative motif shared by proteins that bind to dsRNA. At least some DSRM proteins seem to bind to specific RNA targets. Exemplified by Staufen, which is involved in localisation of at least five different mRNAs in the early Drosophila embryo. Also by interferon-induced protein kinase in humans, which is part of the cellular response to dsRNA.	Domain

This is the N-terminal domain of eukaryotic ribonuclease 3 (RNase III, EC:3.1.26.3). Structure analysis of Saccharomyces cerevisiaeRNase III (Rnt1p) :RNA revealed specific contacts between the N-terminal domain (NTD) dimer and the 5' end region of the tetraloop. Deletion of the NTD led to cleavage at alternative site(s), suggesting that this region increases the precision of the cleavage site selectivity [1].	Domain
