Protein Structure
UniProt Annotation
Function Specific GEF for RhoA activation. Does not activate RAC1 or CDC42. Regulates vascular smooth muscle contractility. Negatively regulates excitatory synapse development by suppressing the synapse-promoting activity of EPHB2. {ECO:0000269PubMed:12775584}.
Subcellular Localization Cell projection, dendrite {ECO:0000250}. Note=Expressed exclusively in dendrites of the developing hippocampus. {ECO:0000250}.
Disease Associations
Tissue Specificity Expressed in the vascular smooth muscle of coronary artery. {ECO:0000269PubMed:12775584}.
