This short domain is about 50 amino acids in length. Its structure shows that it is composed of two beta sheets each of three strands. This domain is found associated with the Pfam:PF07501 domain and it has structural similarity with that domain although it is somewhat shorter [1]. The E domain forms part of a rod like structure.
