| + | [[http://www.uniprot.org/uniprot/PREX1_HUMAN PREX1_HUMAN]] Functions as a RAC guanine nucleotide exchange factor (GEF), which activates the Rac proteins by exchanging bound GDP for free GTP. Its activity is synergistically activated by phosphatidylinositol 3,4,5-trisphosphate and the beta gamma subunits of heterotrimeric G protein. May function downstream of heterotrimeric G proteins in neutrophils. [[http://www.uniprot.org/uniprot/CDC42_HUMAN CDC42_HUMAN]] Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses. Involved in epithelial cell polarization processes. Regulates the bipolar attachment of spindle microtubules to kinetochores before chromosome congression in metaphase. Plays a role in the extension and maintenance of the formation of thin, actin-rich surface projections called filopodia. Mediates CDC42-dependent cell migration.<ref>PMID:14978216</ref> <ref>PMID:15642749</ref> <ref>PMID:17038317</ref> | ||
