FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that binds inositol 1,3,4,5-tetrakisphosphate and stimulates the GTPase activity of Ras p21. This protein functions as a negative regulator of the Ras signalling pathway. It is localized to the cell membrane via a pleckstrin homology (PH) domain in the C-terminal region. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]
PHENOTYPE: Mice homozygous for a targeted null mutation die at E12.5-13.5 of massive subcutaneous and intraparenchymal hemorrhage, probably due to underdeveloped adherens junctions between capillary endothelial cells. At E12.5, edema and severe hemorrhaging is frequently observed in the brain and/or rump. [provided by MGI curators]
