CC -!- FUNCTION: Component of the CCM signaling pathway which is a crucial
CC regulator of heart and vessel formation and integrity. Negative
CC regulator of angiogenesis. Inhibits endothelial proliferation,
CC apoptosis, migration, lumen formation and sprouting angiogenesis in
CC primary endothelial cells. Plays a role in integrin signaling. Plays an
CC important role in the maintenance of the intracellular reactive oxygen
CC species (ROS) homeostasis to prevent oxidative cellular damage.
CC Facilitates the down-regulation of cyclin-D1 (CCND1) levels required
CC for cell transition from proliferative growth to quiescence by
CC preventing the accumulation of intracellular ROS. Probable microtubule-
CC associated protein that may bind to phosphatidylinositol 4,5-
CC bisphosphate (PIP2)-containing membranes (By similarity). Required for
CC correct endothelial cell polarity and cell junction stabilization in
CC cardiovascular development. May play a role in the regulation of
CC macroautophagy through the down-regulation of the mTOR pathway (By
CC similarity). {ECO:0000250, ECO:0000250|UniProtKB:O00522,
CC ECO:0000269|PubMed:21633110, ECO:0000269|PubMed:23007647}.
CC -!- SUBUNIT: Interacts with heg1 and ccm2; greatly facilitates ccm2-binding
CC to heg1. Interacts with rap1. {ECO:0000269|PubMed:19151727,
CC ECO:0000269|PubMed:21633110}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Cell membrane;
CC Peripheral membrane protein. Cell junction. Note=KRIT1 and CDH5
CC reciprocally regulate their localization to endothelial cell-cell
CC junctions (By similarity). Association with RAP1 relocalizes KRIT1 from
CC microtubules to cell junction membranes. {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: Expressed in the ventricular zone of the brain at
CC 28 hours post fertilization (hpf) and at lower levels, throughout the
CC entire brain and in the posterior cardinal vein. Venous expression is
CC maintained at 48 hpf. At the same time, there is also prominent
CC notochord expression. {ECO:0000269|PubMed:16873582}.
CC -!- DOMAIN: The FERM domain mediates binding to rap1.
CC -!- DOMAIN: The N-terminal domain has structural similarity to the nudix
CC hydrolase domain, despite the absence of a nudix box and low sequence
CC similarity with nudix hydrolase domains.
CC {ECO:0000250|UniProtKB:O00522}.
CC -!- DOMAIN: Contains 4 ANK repeats that precede the FERM domain.
CC {ECO:0000250|UniProtKB:O00522}.
CC -!- DISRUPTION PHENOTYPE: The heart chambers in mutant animals are huge,
CC constituted of a monolayered myocardium lined by endocardium.
CC {ECO:0000269|PubMed:16873582}.
