FUNCTION: Functions as a guanine nucleotide exchange factor (GEF), which activates Rac1 and Rac3 Rho small GTPases by exchanging bound GDP for free GTP. Does not have a GEF activity for CDC42. Required for STMN1 'Ser-15' phosphorylation during axon formation and consequently for neuronal polarization. SUBUNIT: Interacts with TSC1. Interacts with nucleotide-free RAC1 and RAC3. SUBCELLULAR LOCATION: Cell projection, axon. Note=Enriched in the developing axons of hippocampal neurons. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=6; Name=1; IsoId=Q96N67-1; Sequence=Displayed; Name=2; IsoId=Q96N67-2; Sequence=VSP_022240, VSP_007707; Name=3; IsoId=Q96N67-3; Sequence=VSP_012440, VSP_022240; Name=4; IsoId=Q96N67-4; Sequence=VSP_012440, VSP_022240, VSP_007707; Name=5; IsoId=Q96N67-5; Sequence=VSP_012440; Name=6; IsoId=Q96N67-6; Sequence=VSP_022240; TISSUE SPECIFICITY: Widely expressed. DOMAIN: The DHR-2 domain mediates GEF activity. SIMILARITY: Belongs to the DOCK family. SIMILARITY: Contains 1 DHR-1 (CZH-1) domain. SIMILARITY: Contains 1 DHR-2 (CZH-2) domain.
