The ELM2 (Egl-27 and MTA1 homology 2) domain is a small domain of unknown function. It is found in the MTA1 protein that is part of the NuRD complex [1]. The domain is usually found to the N terminus of a myb-like DNA binding domain Pfam:PF00249. ELM2 is also found associated with an ARID DNA binding domain Pfam:PF01388 in Swiss:O82364. This suggests that ELM2 may also be involved in DNA binding, or perhaps is a protein-protein interaction domain.
