This domain is found at the N-terminal of hypothetical proteins from yeast that are thought to be the noncanonical Dicers found in these organisms. These proteins adopt a homodimer assembly similar to bacterial ribonuclease III but extended by a unique N-terminal domain that consists of five alpha-helices [1].	Domain

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
