MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a large protein that functions as a GDP to GTP exchange factor. This protein promotes the reorganization of the actin cytoskeleton, thereby playing a role in cell migration and growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
PHENOTYPE: Homozygous mutant mice die during late embryonic development or shortly after birth. They exhibit abnormal skeletal myogenesis and display aberrant organization within the hippocampus and olfactory bulb. [provided by MGI curators]
