Prex1 Gene Summary [Mouse]

Predicted to enable GTPase regulator activity; phospholipid binding activity; and protein serine/threonine kinase inhibitor 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). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Prex1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • Domain found in Dishevelled, Egl-10, and Pleckstrin (DEP)
  • phospholipid binding
  • Domain present in PSD-95, Dlg, and ZO-1/2
  • canonical PDZ domain
  • enzyme binding
  • GTPase activator
  • protein binding
  • Pleckstrin homology-like domain
  • RhoGEF domain
  • DEP
  • RhoGEF
  • guanyl-nucleotide exchange factor
  • PH domain
  • Dbl homology domain
