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]. * **UniProt Summary**: Guanine nucleotide exchange factor (GEF) for RHOA and RAC1 GTPases (PubMed:8643598, PubMed:27418539). Involved in coordinating actin remodeling, which is necessary for cell migration and growth (PubMed:10341202). In developing hippocampal neurons, limits dendrite formation, without affecting the establishment of axon polarity. Once dendrites are formed, involved in the control of synaptic function by regulating the endocytosis of AMPA-selective glutamate receptors (AMPARs) at CA1 excitatory synapses (By similarity). May act as a regulator of adipogenesis (By similarity). {ECO:0000250|UniProtKB:F1M0Z1, ECO:0000269|PubMed:10341202, ECO:0000269|PubMed:27418539, ECO:0000269|PubMed:8643598}. |Pkinase Tyr| |RhoGEF| |Pkinase| |SH3 1| |I-set| |Spectrin| |transmembrane receptor protein tyrosine phosphatase signaling pathway| |negative regulation of fat cell differentiation| |Rho guanyl-nucleotide exchange factor activity| |guanyl-nucleotide exchange factor activity| |regulation of fat cell differentiation| |regulation of Rho protein signal transduction| |regulation of Ras protein signal transduction| |axon guidance| |neuron projection guidance| |regulation of small GTPase mediated signal transduction| |protein serine/threonine kinase activity| |axonogenesis| |axon development| |cell morphogenesis involved in neuron differentiation| |neuron projection morphogenesis| |plasma membrane bounded cell projection morphogenesis| |cell projection morphogenesis| |cell part morphogenesis| |chemotaxis| |taxis| |cell morphogenesis involved in differentiation| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |neuron projection development| |positive regulation of cell death| |negative regulation of cell differentiation| |enzyme linked receptor protein signaling pathway| |cell morphogenesis| |neuron development| |cellular component morphogenesis| |negative regulation of developmental process| |protein phosphorylation| |central nervous system development| |neuron differentiation| |plasma membrane bounded cell projection organization| |cell projection organization| |phosphorylation| |locomotion| |G protein-coupled receptor signaling pathway| |ATP binding| |generation of neurons| |regulation of apoptotic process| |movement of cell or subcellular component| |regulation of programmed cell death| |neurogenesis| |cell development| |regulation of cell death| |regulation of cell differentiation| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp352|Dexamethasone 0.006 to 0.015μM on day4 R07 exp352]]|-1.94| |[[:results:exp187|proTAME 5μM R04 exp187]]|-1.82| |[[:results:exp320|ABT-702 5μM plus CoCl2 18μM R07 exp320]]|-1.81| |[[:results:exp308|Rapamycin 2μM plus FK-506 5μM R07 exp308]]|-1.81| No correlation found to any other genes in chemogenomics.
