Programmed cell death 10 protein (PDCD10/CCM3) is part of the CCM complex and is required for neuronal migration [1]. Outside of this complex, it is crucial in vascularization and in angiogenesis as it functions in vessel permeability and stability [2]. This protein plays an essential role in early embryonic angiogenesis and cardiovascular development [6]. PDCD10/CCM3 interacts with a variety of proteins, including paxillin, membrane receptor vascular epidermal growth factor receptor 2, CCM complex component CCM2 and germinal center kinase III proteins (GCKIII). It consists of a N-terminal dimerisation domain and a C-terminal focal adhesion targeting-homology (FAT-H) domain (Pfam:PF06840) [3]. This entry represents the N-terminal dimerisation domain, consisting of four alpha-helices [3,4,5,6]. This domain is also found at the C-terminal of GCKIIIs (STK24/MST3, STK25, STK26/MST4), which adopts a closely related fold. GCKIIIs are involved in the regulation of apoptosis, cell proliferation, polarity, migration, and cytoskeleton remodelling. This domain mediates homo and heterodimerisation [5,6]. PDCD10/CCM3 forms a heterodimer with GCKIIIs analogous to CCM3 homodimer.	Domain
