arb1

Argonaute-binding protein 1

399 amino acids

Component of the argonaute siRNA chaperone (ARC) complex which is required for histone H3K9 methylation, heterochromatin assembly and siRNA generation. The ARC complex contains mostly double-stranded siRNA. Inhibits the release of the siRNA passenger strand from ago1 together with arb2. Inhibits the slicer activity of ago1. Required for swi6 localization to the centromeric repeats.
