Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable GTPase activator activity; guanyl-nucleotide exchange factor activity; and phospholipid binding activity. Acts upstream of or within several processes, including neutrophil chemotaxis; positive regulation of GTPase activity; and positive regulation of substrate adhesion-dependent cell spreading. Predicted to be located in several cellular components, including dendritic shaft; growth cone; and perinuclear region of cytoplasm. Predicted to be active in plasma membrane. Is expressed in several structures, including liver; nervous system; palatal shelf; skeleton; and testis. Used to study autism spectrum disorder. Orthologous to human PREX1 (phosphatidylinositol-3,4,5-trisphosphate dependent Rac exchange factor 1). PHENOTYPE: Mice homozygous for a null allele have impaired neutrophil migration and autism-like social behavior with defective AMPA-mediated LTD. Mice with other alleles exhibit reduced weight, smaller livers and increased peripheral neutrophil numbers. [provided by MGI curators] |
