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
