Brain 9:28-28(2016). CC -!- FUNCTION: Plasma membrane-associated small GTPase which cycles between CC active GTP-bound and inactive GDP-bound states (PubMed:24352656). In CC its active state, binds to a variety of effector proteins to regulate CC cellular responses such as secretory processes, phagocytosis of CC apoptotic cells, epithelial cell polarization, neurons adhesion, CC migration and differentiation, and growth-factor induced formation of CC membrane ruffles. Rac1 p21/rho GDI heterodimer is the active component CC of the cytosolic factor sigma 1, which is involved in stimulation of CC the NADPH oxidase activity in macrophages. Essential for the SPATA13- CC mediated regulation of cell migration and adhesion assembly and CC disassembly. Stimulates PKN2 kinase activity. In concert with RAB7A, CC plays a role in regulating the formation of RBs (ruffled borders) in CC osteoclasts. In glioma cells, promotes cell migration and invasion. CC Required for atypical chemokine receptor ACKR2-induced LIMK1-PAK1- CC dependent phosphorylation of cofilin (CFL1) and for up-regulation of CC ACKR2 from endosomal compartment to cell membrane, increasing its CC efficiency in chemokine uptake and degradation. In podocytes, promotes CC nuclear shuttling of NR3C2; this modulation is required for a proper CC kidney functioning. In neurons, is involved in dendritic spine CC formation and synaptic plasticity (PubMed:24352656, PubMed:26969129). CC In hippocampal neurons, involved in spine morphogenesis and synapse CC formation, through local activation at synapses by guanine nucleotide CC exchange factors (GEFs), such as ARHGEF6/ARHGEF7/PIX (PubMed:12695502). CC In synapses, seems to mediate the regulation of F-actin cluster CC formation performed by SHANK3. In neurons, plays a crucial role in CC regulating GABA(A) receptor synaptic stability and hence GABAergic CC inhibitory synaptic transmission through its role in PAK1 activation CC and eventually F-actin stabilization (By similarity).
