Cerebral cavernous malformations (CCM) are neurovascular dysplasias affecting up to 0.5% of the population. Mutations in the CCM2 gene are associated with acquisition of CCM. We identify a previously uncharacterized domain at the C-terminus of CCM2 and determine its 1.9A resolution crystal structure. Because this domain is structurally homologous to the N-terminal domain of harmonin, we name it the CCM2 harmonin-homology domain or HHD. CCM2 HHD is observed in two conformations, and we employ analytical ultracentrifugation to test its oligomerization. Additionally, CCM2 HHD contains an unusually long 13-residue 3(10) helix. This study provides the first structural characterization of CCM2. STRUCTURED SUMMARY OF PROTEIN INTERACTIONS: CCM2binds to CCM3 by pull down (View interaction) CCM2 and CCM2bind by X-ray crystallography (View interaction) CCM2 and CCM2bind by molecular sieving (View interaction).
