This is the CC and Ex subdomains found in PH-CC-Ex globular domain from Tiam1 and Tiam2 proteins (T-lymphoma invasion and metastasis). The CC subdomain forms an antiparallel coiled coil with two long alpha-helices, together with the C-terminal Ex subdomain they form a small globular domain comprising three alpha-helices. The CC subdomain of the Tiam2 PHCCEx domain follows the C-terminal alpha1 helix of the PH Pfam:PF00169 subdomain through a four-residue linker [1].	Domain
