Exuperantia (Exu) is associated with localization of bicoid (bcd) mRNA and required for its localization at the anterior pole of the oocyte. 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].	Domain
A, B	PF22123	Exuperantia RNAse H-like domain (Exu_RNase_H_like)	Exuperantia RNAse H-like domain	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 ...	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.	Domain
