Crystal structure of Exu reveals a dimeric assembly with each monomer consisting of a 3'-5' EXO-like domain and a sterile alpha motif (SAM)-like domain. The SAM-like domain interacts with its target RNA as a homodimer and is required for RNA binding activity [1].

The ...This entry represents the RNAse H-like domain found at the N-terminal of exuperantia (Exu) from Drosophila and similar sequences from insects. Exu is a RNA-binding pseudonuclease associated with bicoid mRNA and required for its localization [1]. The catalytic site is degenerate and inactive, then, this domain mediates dimerization and RNA binding.
