Disease
[PDC10_HUMAN] Hereditary cerebral cavernous malformation. Defects in PDCD10 are the cause of cerebral cavernous malformations type 3 (CCM3) [MIM:603285]. Cerebral cavernous malformations (CCMs) are congenital vascular anomalies of the central nervous system that can result in hemorrhagic stroke, seizures, recurrent headaches, and focal neurologic deficits. CCMs have an incidence of 0.1%-0.5% in the general population and usually present clinically during the 3rd to 5th decade of life. The lesions are characterized by grossly enlarged blood vessels consisting of a single layer of endothelium and without any intervening neural tissue, ranging in diameter from a few millimeters to several centimeters.[1]
Function
[PDC10_HUMAN] Promotes cell proliferation. Modulates apoptotic pathways. Increases mitogen-activated protein kinase activity and MST4 activity. Important for cell migration, and for normal structure and assembly of the Golgi complex. Important for KDR/VEGFR2 signaling. Increases the stability of KDR/VEGFR2 and prevents its breakdown. Required for normal cardiovascular development. Required for normal angiogenesis, vasculogenesis and hematopoiesis during embryonic development (By similarity).[2] [3] [4]

Publication Abstract from PubMed
Programmed cell death 10 (PDCD10) is a novel adaptor protein involved in human cerebral cavernous malformation, a common vascular lesion mostly occurring in the central nervous system. By interacting with different signal proteins, PDCD10 could regulate various physiological processes in the cell. The crystal structure of human PDCD10 complexed with inositol-(1,3,4,5)-tetrakisphosphate has been determined at 2.3A resolution. The structure reveals an integrated dimer via a unique assembly that has never been observed before. Each PDCD10 monomer contains two independent domains: an N-terminal domain with a new fold involved in the tight dimer assembly and a C-terminal four-helix bundle domain that closely resembles the focal adhesion targeting domain of focal adhesion kinase. An eight-residue flexible linker connects the two domains, potentially conferring mobility onto the C-terminal domain, resulting in the conformational variability of PDCD10. A variable basic cleft on the top of the dimer interface binds to phosphatidylinositide and regulates the intracellular localization of PDCD10. Two potential sites, respectively located on the two domains, are critical for recruiting different binding partners, such as germinal center kinase III proteins and the focal adhesion protein paxillin.
